Studies of natural frequency degradation and the nature of destruction of reinforced concrete frames in case of an earthquake
Authors: Mkrtychev Oleg , Zaitsev Roman
Published: August 2023

The article presents the results of a numerical study of the impact of local damage to load-bearing structures on the degradation of natural frequencies and the integrity of the structure during an earthquake. The research was carried out using LS-DYNA software complex, which implemented Continuous Surface Cap Model (CSCM), the nonlinear model of concrete. The design model of a reinforced concrete building is modeled using volume finite elements for concrete, and rod finite elements for reinforcement. A two-storey building with a frame structural diagram was chosen as an object of modelling. Studies have shown a significant (up to 22%) decrease in the frequencies of natural oscillations during an earthquake of 8 points intensity. This suggests that damage appears in the structure and overall stiffness of the building decreases. Attempting to estimate damage using the percentage of failed items shows that structural damage exceeds 7%. Analysis of the results shows that the most intense decrease in the frequencies of natural oscillations occurs during the active phase of the earthquake. When the active phase ends, the frequencies stabilize and stop decreasing. The LS-DYNA software package allows to perform studies of the impact of local damage to load-bearing structures on the dynamic properties during an earthquake when concrete is reinforced with reinforcement bars, and can be used in calculations and design of buildings and structures.

Plasticity of anchors in damaged by earthquake concrete base
Authors: Kovalev Mikhail , Kabantsev Oleg
Published: August 2023

Most frequently used types of anchors were subjected to experimental studies to obtain valid data on post-installed anchors, such as mechanical anchors (wedge expansion anchors, undercut anchors); bonded anchors (with epoxy resin) and bent cast-in-place anchors. The authors studied the effect of an earthquake-induced damage (plastic deformation) of a concrete base and multi-cyclic dynamic loads, similar to seismic ones, on plasticity of anchors. Plastic phase deformation in case of reinforced concrete base was simulated as a system of cracks of different opening width. The results of the research show that increase in the width of the crack opening from 1.5 to 3.0 mm leads to a decrease in the values of the plasticity factors. Dynamic loading does not lead to a significant change in the plasticity factor related to static loading for all failure mechanisms, except for the bond failure. On the base of obtained results reduction factors of seismic loads may be determined for further calculation of anchor joints subjected to seismic impact.

Authors: Tran Ngoc-Long , Le Xuan-Vinh , Nguyen Van-Hoa
Published: August 2023

Selecting the right construction formwork solution is vital to the success of a construction project. It can help speed up the construction schedule, boost quality, reduce construction costs, and ensure the safety of workers on the construction site. Construction contractors should carefully consider the project’s characteristics and their capacity when selecting the most suitable formwork solution. The Analytic Hierarchy Process (AHP) method is a decision-making tool that can be useful in selecting the best formwork solution for constructing high-rise buildings. The AHP method allows decision-makers to break down complex decisions into smaller, more manageable parts and to evaluate alternatives based on a set of criteria. The paper presents the process and propose the use of the method in selecting formwork options.

Published: August 2023

The development of computer science has promoted the application of scientific and technological achievements to construction engineering in general and steel structure design in particular. Recently, the steel frame structure design has applied advanced analytical methods to take into account the inelastic behavior of the material and the geometric nonlinear properties of the structure, leading to the results obtained close to the real structure. In addition, to reduce computational time and effort, it has been applied advanced machine learning (ML) algorithms to predict behavior, helping to accelerate decision-making, improve efficiency, and reduce errors. In this paper, 5 popular machine learning algorithms are currently being conducted for the regression-based to estimate the ultimate load capacity of steel frames, including Linear Regression, Deep Learning, Support Vector Machine, Random Forest, and XGBoost. The effectiveness of applying these methods is tested through a numerical example surveying a 20-story space steel frame. The performance of ML algorithms is evaluated by comparing the mean-squared error (MSE) and computational efforts. The results show that among the 5 selected methods, the XGBoost has obvious advantages and is superior in terms of both MSE and calculation time.

Authors: Vu Ngoc Tuyen , Fedorova Natalia , Tyurina Vasilina , Duong Thanh Qui
Published: August 2023

Variants of diagrams for the description of the stress-strain state of concrete under uniaxial and volumetric stress state at different levels and stages of deformation have been considered. A variant of nonlinear analytical dependence between stresses and relative deformations of concrete under uniaxial stressed state described by one continuous polynomial function over the entire range of deformation, including the description of the range of limiting deformations on the descending branch of the diagram, is proposed. The obtained dependence has a number of advantages for the calculation of reinforced concrete structures compared to other known variants of diagrams. The use of this dependence as the initial characteristics of concrete properties in the defining relations to describe the volumetric stress state of concrete more fully corresponds to the physical meaning of the law of deformation of concrete, has sufficient accuracy and can be recommended for practical use in the design of reinforced concrete structures.

Authors: Berger Maria , Mylnikov Ivan
Published: August 2023

Concrete-steel composite structures are unique structures that combine the advantages of both steel and concrete. Their application is especially relevant in cases where construction objects need to withstand high loads with small cross-sectional dimensions. Thanks to the factory production of most of the elements and easy installation, it is possible to significantly reduce construction times. The main areas of application are high-rise construction, industrial construction, and bridge construction. The main task in the design of concrete-steel composite structures is to take into account the joint work of a reinforced concrete slab and steel beams, i.e. correct modeling of the structure when using calculation systems. This article explores various options for setting the numerical model of a concrete-steel composite beams using the example of one floor of a high-rise building, evaluates their reliability and compliance with the actual behavior of the structure. In conclusion, recommendations are offered on the numerical modeling of concrete-steel composite beams for calculation using the finite element method.

Authors: Pham Ngoc Hieu
Published: August 2023

The paper investigates the strength and behavior of the portal steel frame under the consideration of working 3D models. In terms of design, the industrial buildings have been separated into a single portal frame to simplify the design process. This point of view is suitable for structures in that the applied loads are equally distributed to all frames. The fact that the crane loads including vertical and horizontal loads only directly affected one or several portal frames. Therefore, a 3D model of a whole single-story steel industrial building is simulated in a finite element software program to study the internal forces and deformations of this building in comparison with those values of a model of a separated portal steel frame. Based on these comparisons, significant conclusions can be given, and recommendations are provided for designers.

Authors: Modestov Konstantin , Saiyan Sergey , Erokhin Artyom , Brygar Oleg
Published: August 2023

With the rapid development of engineering science and technology, tasks related to the calculation of wave processes in elastic medium are becoming more and more relevant. One of the important problems is the search for effective methods for calculating the propagation of harmonic oscillations in elastic mediums, in particular, in semi-infinite spaces. One of these methods is the use of asymptotic boundary conditions of the “radiation conditions” type, which allow us to describe the processes of wave propagation outside the computational domain. In this paper we consider the application of infinitesimal viscosity to derive an asymptotic boundary condition of the “radiation condition” type for the propagation of harmonic oscillations in a semi-infinite elastic space. The results of the study can be used in the design of various devices and structures subjected to the influence of wave processes in elastic mediums, in particular, in the field of soil mechanics.
Penalty function method for geometrically nonlinear buckling analysis of imperfect truss with multi-freedom constraints based on mixed FEM
Authors: Bich Quyen Vu Thi , Ngoc Tien Dao , Thuy Van Tran Thi
Published: August 2023

This paper is concerned with the approach to implementing the Penalty function method for imposing multi-freedom constraints in geometrically nonlinear analysis of imperfect trusses based on mixed finite element formulation. Using a finite element model based on displacement formulation, it is required to incorporate both the dependent boundary relations and initial length imperfection to the nonlinear master stiffness system of equations for solving the geometrically nonlinear problem of imperfect truss with multi-freedom constraints. For decreasing the mathematical complexion of the incorporating process, the author proposes a novel mixed finite truss element considering initial imperfection, used in building the model for solving the geometrically nonlinear problem of truss with multi-freedom constraints. The modified nonlinear stiffness equation is constructed by employing the penalty function method to convert a constrained problem into an unconstrained problem by extremizing the augmented energy function established based on the proposed mixed finite element formulation. For solving the nonlinear equilibrium equation of imperfect trusses with multi-freedom constraints, the incremental equilibrium equation is constructed, and the incremental-iterative algorithm for calculation is established utilizing the arc-length method, used for writing the calculation program for investigating geometrically nonlinear behavior of imperfect truss with multi-freedom constraints. The results of the numerical test show the influence of initial imperfection and choosing weight values on the equilibrium path of the truss.
An algorithm for analyzing the reactive behavior of structural elements of panel buildings
Authors: Mondrus Vladimir , Kulikov Vladimir
Published: August 2023

The paper considers the reactive aspects of the behavior of structural elements of large-panel housing construction. The problem of determining the position in space of the material point (center of mass) of the objects under study is solved, thus allowing us to evaluate the kinetics of the behavior of structural elements as a whole. Original design schemes are proposed with respect to all spatial axes to determine the dynamic reactions of structural elements’ connections under pulsed dynamic action on buildings and structures. A system of local oscillator forces balanced by inertial internal and external influences has been compiled by the method of kinetostatics. The interpretation of the behavior of structural elements of buildings by various oscillators is proposed. This interpretation allowed the periodic harmonics to quantify the change in kinetic energy of structural elements as a result of their impact on each other due to external pulsed dynamic influences. An algorithm for determining dynamic reactions in the junctions of structural elements has been developed and proposed.

Published: August 2023

This paper discusses the technological and design features of houses built from local clay materials, in particular, those built from a wooden frame filled with clay materials called “synch” and from adobe or clay materials of irregular shape “pakhsa”. Such buildings built from local materials, as a rule, related to buildings with walls made of low-strength materials, were mostly erected without observing technological, anti-seismic measures and are characterized as the most vulnerable in seismic terms. A comparative analysis of the technology of erection by the owners themselves with some violations and the technology of erection proposed by us in compliance with the rules during the construction process was carried out. In houses built using the “synch” technology, foam balls (expanded polystyrene) were used as a filler to reduce the mass of clay, the optimal ratio of clay and expanded polystyrene was revealed, in the course of research we received a patent for a modified clay material with expanded polystyrene. And also, the results of testing models of houses built from a wooden frame filled with clay materials (synch) and from clay materials using the “pakhsa” technologies are given.

The change of technological and managerial processes caused by scientific and technological progress and designated in the state strategy as the digital transformation should be reflected in the qualitative transformation of organizational structures and methods of implementation of investment and construction activities both at the corporate level and at the industry level. This qualitative transformation is commonly referred to as re-engineering. As a practice and as a methodology reengineering has in its genesis certain phenomena, and for justification uses theoretical tools advised by them. In this regard, the authors in the article argue that digital transformation should be a component of a deeper change in the sectors of the national economy -technological transformation.

In terms of practical value reengineering for the industry and its corporate level can be seen as an effective technology for managing the timing and cost of construction, taking into account the needs of the population in the formation of a comfortable and safe environment of life.
Organizational issues during the liquidation of buildings
Authors: Kuzhin Marat
Published: August 2023

In the presented study, an analysis of issues related to the organization of construction processes during the liquidation of buildings under various conditions was carried out. The main questions in this case are questions of analysis of the initial data, questions of the choice of means of mechanization and the selection of the numerical and qualification composition of workers. In addition, the analysis of factors influencing technical and economic indicators is of great importance. Under the liquidation of objects means the demolition and dismantling of buildings. Demolition and dismantling of buildings can be carried out under various conditions. These conditions can be classified according to the following criteria: by the type of construction activity, within the framework of which the liquidation of the object is carried out; by type of objects to be liquidated; by designation of objects subject to liquidation, to which special conditions are imposed; according to the conditions of spatial limitation of the production of works; according to the conditions of the organization of work. Demolition and dismantling works are extremely dangerous for the life and health of people involved in the liquidation of the facility and the population living or located in close proximity to the construction site and also bear the risk of harm to the environment, movable and immovable property of individuals and legal entities, persons and engineering infrastructure. Therefore, to ensure the safety of the work performed, it is necessary to have a set of standards that establish the rules for the design of organizational and technological documentation for demolition or dismantling, the performance of work during the liquidation of the facility and strict control over the implementation of technology and safety. The study of the processes of demolition and dismantling of buildings for residential and civil purposes showed that there are many unresolved issues related to the organization of this type of construction work. When organizing liquidation, it is necessary to make scientifically based decisions. The feasibility study is based on taking into account the influence of various factors on the construction industry and evaluating a set of solutions for planning the execution of work. The study of this issue will reduce the costs of organizing this type of work and make science-based decisions. The development of a technical and economic mechanism is a necessity for the development of the modern construction industry.

Published: August 2023

The XXI century has confronted humanity with a number of global environmental and social problems. Some of them depend on the construction industry. The tasks of ensuring the sustainability of construction have become relevant. The article discusses modular construction as one of the most promising ways to achieve the requirements of sustainable construction. The purpose of the study is to analyze the prospects for the implementation of modular construction technology based on modern digital technologies to achieve the objectives of sustainable construction. The analysis of modular construction materials is carried out. The main advantages of using modular technologies (efficiency, quality, speed, environmental friendliness) are determined. Increasing the degree of automation and the introduction of modern digital technologies is a promising direction for the development of modular construction. It is noted that the promising areas of production automation are robotic machines, manipulators and 3D printers. It is noted that the use of BIM technologies is necessary to automate the design process. The digital information model allows to collect all the information about a modular object and its components and to use it at all stages, including the manufacture of structures. Generative design in combination with BIM allows to automate the synthesis of design solutions according to specified requirements. As a result of the research, a scheme for integrating BIM, generative design and modern factory production facilities into a single digital production chain of modular construction is proposed. Such chain is a bundle of a virtual conveyor of information models based on generative design and a factory production system with the use of 3D printing to manufacture structures according to the specifications of the information model. The system of synthesis of design solutions on the base of the system of generative algorithms is proposed. Examples of local optimization problems of generative design for modular construction are presented. The conclusion is made about the need for a comprehensive application of the considered technologies to achieve the greatest efficiency of construction.
The influence of green roofs on reducing storm runoff
Authors: Sysoeva Elena , Bogachev Aleksey
Published: August 2023

The present research studies the way to reduce storm runoff in urban conditions by means of installing green roofs when projecting, constructing, re-constructing buildings, as well as performing major repairs. Sewer systems of rapidly growing modern cities are often unable to cope with the load. This is why today environmentally friendly and efficient reduction of storm runoff is one of the major challenges in the field of urban development. Despite the fact that foreign research on the topic and the experience of applying the green roof technologies abroad proved considerable reduction of runoff, the question of feasibility of this method in the Russian reality remains open. It is important to take into account not only water-retaining capacity of green roofs per se, but also meteorological features of the area of the planned construction, production technology methods and used building materials. Until now, little attention has been paid to this subject in the Russian Federation, which has consequently delayed the introduction of modern green roof technology in our country, as well as the development and approval of the necessary regulatory framework. The article provides theoretical proof of the efficiency of green roofs in reducing storm and snowmelt runoff in the climate conditions of Central Russia based on statistical and empirical data. The results obtained may prove valuable for further development of green technologies in construction and for ensuring environmental safety in our country.

The influence of the characteristics of external finishing coatings on the humidity regime in walls made of aerated concrete grades D350-D500 for buildings located in the geographic subregion of Northeast Asia has been assessed. The temperature of the onset of condensation has been determined depending on the type of finishing layer. The amount of condensed moisture in the fence in winter is calculated. The humidity regime in the walls was compared for the conditions of the Russian cities of Khabarovsk and Vladivostok, as well as for cities located in China close to the border with Russia - Beijing and Harbin. It has been established that the humidity regime of walls made of aerated concrete grades D350-D500, for the considered cities of China, to a greater extent, in comparison with the considered cities of Russia, depends on the characteristics of the external finishing coating.
Stability of dam slopes taking into account anisotropy
Authors: Bestuzheva Alexandra , Abduloev Alisher
Published: August 2023

This paper presents the results of experimental studies on the deformation and strength anisotropy of gravel-pebble soils used in soil dams. During stabilometric tests, varying shear angles were obtained for stone at different orientations of soil particles in the working chamber, whether horizontal or vertical. As the hydrostatic pressure in the working chamber increased to 0.8 MPa, a reduction of shear angles of a stone by 8-12 degrees depending on the direction of layering of soil was observed. The authors compiled a calculation program called OTKOS_Ani (Delphi), which considers the strength anisotropy of pebble soils for calculating the stability of slopes of soil dams and slopes. The slope calculations were carried out for different design and height of stone and stone-soil dams, and correction factors for taking into account the strength anisotropy in slope stability calculations, kан, were obtained depending on the type, height, and density of gravel-pebble soil stacking in the dam body. The results showed that considering the anisotropy of strength properties in the calculations of slope stability of earth dams reduces the safety factors by 3-11%. This should be taken into account when selecting the design of earth dams with prisms of gravel-pebble soils.

The purpose of the reconstruction of the canal is to avoid the pumped irrigation and the high water consumption associated with it, and change to gravity irrigation with increased efficiency through the implementation of reliable waterproofing measures.In addition, to provide irrigation water to command areas of 100 thousand hectares, Ellikal’a, Beruni and Turtkul regions, the canal is constructed in the fill,partially semi-excavation and semi-fill. The canal is located in the sandy areas and,accordingly the embankment is constructed using sandy material with layer-by-layer compaction to achieve a density of 1.66 g/cm3. Concrete class B25 with thickness 12cm, was laid on geotextile and geomembrane 1.5 mm thick. The main objective of the field research of the constructed section was to check water tightness and durability of the work completed.The field investigationswere carried out on two experimental sections of the Bustan canal in 50 m length, from PK47 + 55 to PK 48 + 00 and from PK 266 + 37 to 265 + 87. Here are results of investigation on the first experimental section which were carried out from 12/15/2021 to 12/21/2021 for 7 days. During the seven days, observations were made of leakage along the side embankments, outer slope of the canal embankments, and evaporation from the surface of ponding canal section was also measured. Evaporation of water during this time was3.5 mm/day, i.e., the water level in the experimental section was decreased only due to the loss of evaporation. During the observation period, leakage of water was not observed, which indicates sufficient reliability of water tightness, concrete lining and geomembrane.

Hundreds of resumes are received, processed, and managed by large companies and recruitment agencies. Furthermore, many people post their resumes on the internet. Organizations all across the world, on the other hand, are battling to locate the greatest resource. To complete this work, these organisations rely on industry expertise. Manual interaction is required in the resume screening process. Most of the current technologies search for keywords but do not consider semantics, resulting in many superfluous resumes being shortlisted. The goal of the proposed study is to create a smart resume screening algorithm that can automatically retrieve and process resumes. Name, phone / cell numbers, e-mail addresses, qualification, experience, skill sets, and other fields are mapped to the retrieved data. The proposed model uses AI and ML techniques to do so. The gathered data can be utilised to develop applicant profiles that meet the organization’s recruitment needs. By applying multiple filters to the data, an efficient man-less screening process can be achieved. The model is applied to the resumes that the company receives. The model has performed with an average accuracy of more than 90%. The model can be enhanced to apply on the resumes written in languages other than English.

Authors: Bhuyan Hemanta Kumar , Kumar Vikash , Brahma Biswajit
Published: August 2023

The cause of blindness that primarily affects middle-aged adults is diabetic retinopathy (DR), due to excessive blood sugar levels. Internet of Medical Things (IoMT) is capable to collect Diabetic Retinopathy-related information remotely using CAD (Computer-aided diagnostic) systems and provide patients with convincing information. Therefore, the primary goal of this study is to identify and categorize the severity of DR fundus images to prevent a diabetic sufferer from going blind. Thus, this paper developed a unique Diabetic Retinopathy Segmentation (DRS) system by fusing the Deep Learning model with optimization techniques. The preprocessing phase of this system is considered to remove noise from the edges. Next, the usable region from the images is extracted using the increasing region segmentation through K-mean clustering. The characteristics of the Area of Interest (AOI) are then extracted and classified into four severity levels using the suggested Hybrid Genetic and Ant Colony Optimization (HGACO) algorithm with the help of a pertained CNN model, Residual Neural Network (RESnet). Additionally, the test of statistical significance evaluates the DRS system’s Segmentation accuracy. The suggested Diabetic Retinopathy System achieves improved categorization outcomes, with sensitivity, accuracy, and specificity numbers.

Apart from contemporary attacks, we refer some of the peculiar attacks including DOS, DDOS, bot attack, Mantis Botnet, Mirai Botnet etc. These attacks jeopardize the security systems. To overcome the situation, we propose an architecture, which makes use of modified DES encryption followed by Hamming code. In transmitter section, the 256-bit input data is encrypted by 224-bit cipher key, which is then encoded with Hamming code (448, 256) to produce 448-bit of encrypted data. The reverse scheme is applicable in receiver section. We have used Xilinx software to simulate the proposed model. Simulation results show that the duration of both the encryption and encoding are in nano seconds. The intruders shall get very less time to interfere. Therefore, the proposed architecture shall improve the security in current 5G communication systems.
Dépistage des affections de l’appareil respiratoire supérieur : actualités diagnostiques
Authors: Robert Mickaël , Hermange Tanguy
Published: August 2023

Une fois l’examen clinique réalisé, diverses techniques d’imagerie sont utilisables pour investiguer l’appareil respiratoire supérieur du cheval. L’endoscopie au repos permet d’observer aisément l’aspect luminal des cavités nasales, du pharynx, du larynx, des poches gutturales et de la trachée. Elle permet d’apprécier l’anatomie de ces structures, d’avoir une idée de la fonction laryngée et de détecter des anomalies pathologiques. De petits endoscopes rendent aujourd’hui possible une exploration sinusale directe. L’endoscopie dynamique est la technique de choix pour investiguer la fonction laryngée à l’effort en cas de bruit respiratoire ou de contre-performance, quelle que soit la discipline du cheval. La radiographie garde une place importante dans le diagnostic des affections respiratoires supérieures, notamment des sinus et structures associées. Toutefois les superpositions dans la région de la tête peuvent rendre son interprétation difficile. L’échographie laryngée permet d’évaluer les structures extra-luminales et d’évaluer sa fonction. Elle est notamment intéressante dans le diagnostic du déplacement du voile du palais, de l’hémiplégie laryngée ou de la dysplasie laryngée. Le scanner est aujourd’hui considéré comme la technique de choix dans l’évaluation des cavités nasales et des sinus du cheval. Il permet de s’affranchir des superpositions rencontrées en radiographie classique et est réalisable facilement sur cheval debout tranquillisé dans certaines structures hospitalières. L’IRM et la scintigraphie, quoique moins disponibles, peuvent également avoir un intérêt dans l’évaluation des voies respiratoires supérieures du cheval.
Affections du pharynx chez le cheval: Actualités diagnostiques et thérapeutiques
Authors: Pader Karine
Published: August 2023

Le pharynx est une structure musculaire qui doit s’adapter à des changements extrêmes en matière de pression inspiratoire/expiratoire ou de volumétrie lors de l’effort. Ceci est rendu possible par sa musculature intrinsèque et extrinsèque complexe. L’affection dynamique la plus fréquente est le déplacement dorsal intermittent du voile du palais (DDIVP), dont l’incidence est estimée entre 20 et 30 % chez les chevaux de course de 2 et 3 ans. Le traitement du DDIVP passe par des mesures conservatrices et un traitement médical avant qu’un traitement chirurgical ne soit proposé. Les autres affections pharyngées plus rares sont la fente palatine ou encore l’atrésie des choanes chez le poulain, ainsi que la cicatrice pharyngée ou les masses pharyngées chez l’adulte. Compte tenu du caractère congénital de l’atrésie des choanes ou de la fente palatine, les chevaux affectés doivent être exclus de la reproduction s’ils survivent au traitement chirurgical.
Nouveautés dans le diagnostic et le traitement des affections des sinus paranasaux chez le cheval
Authors: Pouyet Morgane
Published: August 2023

Les sinus paranasaux du cheval sont composés de sept cavités différentes et peuvent être affectés par des maladies très diverses. Les techniques diagnostiques traditionnelles (endoscopie, radiographie, sinusoscopie) peuvent être invasives et ne permettent pas toujours d’obtenir un diagnostic précis. Des études récentes ont cherché à pallier ces défauts en développant des techniques permettant l’accès aux sinus par endoscopie depuis les cavités nasales ou encore de réaliser une sinusoscopie de manière minimalement invasive. Pour le moment, le scanner reste le meilleur outil pour diagnostiquer les maladies sinusales, en particulier pour les sinusites d’origine dentaire. L’IRM, plus couteux et plus difficile d’accès, est intéressant pour le diagnostic des tumeurs.

Le traitement chirurgical des sinusites peut être difficile et comporte de nombreuses complications. Afin de diminuer le taux de morbidité, des travaux récents ont permis de mettre au point différentes techniques visant à améliorer le drainage des sinus vers les cavités nasales, limiter les risques d’hémorragies et faciliter le traitement des affections bilatérales et des fistules cutanées.
Study of relaxation processes in a two-phase flow model
Authors: Bussac Jean
Published: August 2023

This work concerns the analysis of the relaxation processes toward thermodynamical equilibrium arising in a compressible immiscible two-phase flow. Classically the relaxation processes are taken into account through dynamical systems which are coupled to the dynamics of the flow. The present paper compares two types of source terms which are commonly used: a BGK-like system and a mixture entropy gradient type. For both systems, main properties are investigated (agreement with second principle of thermodynamics, existence of solutions, maximum principle,...) and numerical experiments illustrate their asymptotic behaviour.
Pressure relaxation in some multiphase flow models
Authors: Herard Jean-Marc , Jomée Guillaume
Published: August 2023

We consider in this paper multiphase flow models involving two, three or four fields, in total mechanical and thermodynamical disequilibrium. Thus several pressure fields arise, and we precisely focus here on the pressure relaxation process, while restricting to four distinct multiphase flow models. The first two models only involve immiscible compressible components, while the last two hybrid models involve both miscible and immiscible components. It is shown that some -weak- restrictions may occur on pressure gaps, which are unlikely to appear in practice. Evenmore, three-phase flow models may involve a non-monotone behaviour in the return to pressure equilibrium.
