AVKSENTIY TSEZAREVICH PUNI AND HIS LEGACY IN PSYCHOLOGICAL SCIENCE AND PRACTICE
Authors: Бочавер К.А. , Хвацкая Е.Е.
Published: July 2024

В статье описывается жизненный путь, профессиональное становление, идеи и научное наследие Авксентия Цезаревича Пуни. Красноармеец, прошедший Гражданскую и Великую Отечественную войну, он дал старт развитию целой отрасли советской науки – психологии спорта и физической культуры, основав сильнейшую в стране и в мире ленинградскую школу. В статье подробно разбираются основные направления его работы и достижения на поприще лечебной физкультуры, спортивной психологии, организации работы кафедры, создания научной школы. К числу его учеников относятся наиболее известные в нашей стране и во всем мировом научном сообществе психологи спорта. Несмотря на кажущийся узкопрофессиональный характер эмпирических исследований, колоссальная эрудиция Авксентия Цезаревича и обобщение знаний о психологии тренировочной и соревновательной деятельности, волевой подготовке и личности спортсмена делают его работы не только интересными и актуальными спустя значительный срок после публикации, но также могут внести значительный вклад в другие отрасли психологии. Так, общие принципы подготовки к решающим соревнованиям, идея состояния «боевой» готовности (оптимального состояния), пути сохранения психической свежести и множество других находок и выводов позволяют полноценно опираться на опыт А.Ц. Пуни и его научной школы при работе в русле военной и экстремальной психологии, эргономики и психологии труда, психотерапии и профилактике.

The article describes the life path, professional formation, ideas and scientific legacy of A.C. Puni. A Red Army soldier who passed the Civil War and World War II, he launched the development of an entire branch of Soviet science – the psychology of sport and exercise, founding the strongest Leningrad scientific school. The article examines in detail the main directions of his work and achievements in the field of physical therapy, sport psychology, the organization of the department, the creation of a scientific school. Among his students are the most famous sports psychologists in our country and in the entire world scientific community. Despite the seemingly narrowly professional nature of his empirical research, the colossal erudition of A.C. Puni and the generalization of knowledge about the psychology of training and competitive activity, volitional training and personality of an athlete make his work not only interesting and relevant a considerable time after publication, but can also make a significant contribution to other branches of psychology. Thus, the general principles of preparation for decisive competitions, the idea of a state of "combat readiness" (optimal state), ways to preserve mental freshness and many other findings and conclusions allow us to fully rely on the experience of A.C. Puni and his scientific school when working in line with military and extreme psychology, ergonomics and labor psychology, psychotherapy and prevention.

Authors: Авдотьин В.П. , Авдотьина Ю.С.
Published: July 2024

В анализ экономических последствий чрезвычайных ситуаций (ЧС) и оценке устойчивости экономические модели межотраслевого баланса (модель «затраты – выпуск», экономико-математическая балансовая модель) характеризующие межотраслевые производственные взаимосвязи в экономике страны стали играть заметную роль в анализе последствий ЧС и оценке устойчивости. Эти модели привлекают внимание к различию между прямыми экономическими потерями и каскадными эффектами, которые могут возникнуть внутри многоотраслевой экономической системы в результате ЧС. Расширение возможностей системы анализа межотраслевого баланса имеет решающее значение для адекватной оценки последствий ЧС в отраслевом и региональном разрезе. В статье представлены различные аспекты моделирования ЧС, а также оценка экономической устойчивости с использованием экономико-математических моделей межотраслевого типа.

In the analysis of the economic consequences of emergency situations (ES) and the assessment of sustainability, economic models of intersectoral balance (input-output model, economic-mathematical balance model) characterizing intersectoral production relationships in the country’s economy began to play a prominent role in the analysis of the consequences of emergencies and assessment of sustainability. These models draw attention to the difference between direct economic losses and the cascading effects that can arise within a multi-sectoral economic system as a result of a disaster. Expanding the capabilities of the system for analyzing the intersectoral balance is crucial for adequately assessing the consequences of emergencies at a sectoral and regional level. The article presents various aspects of emergency modeling, as well as assessing economic sustainability using economic-mathematical models of an intersectoral type. Structure of the article: introduction, models of inter-industry balance, presentation of emergencies in the system of input balance, methods of input balance for analyzing the consequences of emergencies, dynamic methods, balance models and sustainability assessment, conclusions, references.

В данной статье приведён пример технологических решений, направленных на уплотнение сетки скважин на карбонатных коллекторах Беркет-Ключевского нефтяного месторождения Республики Татарстан. Рассмотрены различные варианты по дальнейшей разработке залежи нефти с использованием геолого-гидродинамического моделирования. Показаны результаты прогнозных технико-экономических показателей разработки от предлагаемых технологических решений, направленных на увеличение степени выработки запасов в межскважинном пространстве и повышение конечного коэффициента извлечения нефти.

Traditional approaches to oil field development at late stages result in localization of a substantial portion of oil reserves in the inter-well space. Today, a number of effective technological solutions aimed at recovery of residual oil reserves in producing fields are available. One of the approaches to addressing the problem of recovery of residual oil reserves locked in poorly drained and stagnant zones provides for infill drilling. The paper presents an example of infill drilling operations conducted in carbonate reservoirs of Berket-Klyuchevskoye oil field in the Republic of Tatarstan. Various options for further development of the field using geological and reservoir simulation modeling are considered. Forecast production data due to application of proposed technological solutions aimed at enhancing oil recovery in the inter-well space and increasing the ultimate oil recovery factor are presented.

Las setas, son organismos eucariotas con una estructura simple de hifas, desarrollándose en diversas condiciones gracias a sus bajos requerimientos nutricionales. Desempeñan roles cruciales en los ecosistemas, como la descomposición de materia orgánica y simbiosis con plantas. Existen alrededor de 21 679 especies de macrohongos descritas globalmente, y en Ecuador se estima unas 144 783 especies. El objetivo de este estudio fue analizar la historia de los hongos comestibles con un énfasis especial en Ecuador evaluando la situación actual. Materiales y Métodos: Se realizó una revisión exhaustiva de literatura en bases de datos académicas sobre el uso de macrohongos desde 2004 hasta 2024. Se seleccionaron estudios relevantes tras evaluar títulos y resúmenes. Resultados: Los hongos han existido por millones de años, con registros fósiles del Devónico y Cretácico. Su consumo humano data del Paleolítico Superior, evidenciado en cálculos dentales de la "Dama Roja" en España. La aculturación tras la conquista española limitó el uso de hongos, aunque su uso persiste en comunidades indígenas contemporáneas. La micología ecuatoriana aún es un campo emergente, con estudios limitados sobre especies usadas por comunidades indígenas. Especies encontradas en Ecuador han sido estudiadas extensamente en Asia, donde se reconocen por sus propiedades medicinales y aplicaciones industriales. Conclusiones: Estos hallazgos indican que los hongos identificados y recolectados en comunidades indígenas ecuatorianas podrían tener aplicaciones significativas en varios campos por lo que su preservación e identificación no son solo importantes por ser parte del patrimonio de las comunidades indígenas sino también para el desarrollo nuevas aplicaciones científicas y comerciales.
Hydrogen Oxidation and Evolution Reaction on Platinum in Alkaline Electrolyte: Fixed Reference vs. Overpotential and the Effect of H2 Concentration
Authors: Heinritz Adrian , Binninger Tobias , Herranz Juan , Rodriguez Paramaconi , Schmidt Thomas J.
Published: July 2024

Understanding the kinetics of the electrochemical hydrogen oxidation and evolution reaction (HOR/HER) in alkaline media is of great interest, but the underlying reaction mechanism and the dependency on the hydrogen partial pressure are still debated. In this work, we investigated the HOR/HER kinetics on a polycrystalline platinum electrode in alkaline electrolyte using the rotating disk electrode (RDE) technique. Unlike typically done, we rigorously performed data treatment and analysis on a fixed potential scale with a fixed reference potential, which has implications for the use and assessment of RDE mass-transport corrections and the definition of reaction orders. Analyzing the kinetic current curves on a fixed potential scale, we find reaction orders with respect to the hydrogen partial pressure of essentially one and zero for the HOR and HER, respectively, at larger overpotentials. In contrast, fitting the kinetic current curves in a potential range around equilibrium with a generalized Butler-Volmer model yields differing kinetic parameters and fractional reaction orders. Our findings can be explained with a potential-dependent transition in the HOR mechanism from Tafel-Volmer with a rate-determining Volmer step at small overpotentials to Heyrovsky-Volmer with a rate-determining Heyrovsky step at more positive overpotentials, with a concomitant change in the H2 reaction order from fractional to unity, thus reconciling previous propositions in the debate on the alkaline HOR/HER mechanism. Our results demonstrate the strength and advantages of using a fixed potential scale rather than the commonly employed overpotential, and we expect this approach to be beneficial also for kinetic studies of other electrocatalytic reactions.
Visible-Light-Driven Synthesis of Alkenyl Thiocyanates: Novel Building Blocks for Diverse Sulfur-Containing Molecular Assembly
Authors: F. Piedra Helena , Plaza Manuel
Published: July 2024

The first visible-light-induced protocol for the general preparation of alkenyl thiocyanates from alkenyl bromides is presented. The reaction is simple, proceeds under very mild conditions and demonstrates broad functional group tolerance. Additionally, a flow protocol was developed to enable efficient scale-up of alkenyl thiocyanate synthesis, further enhancing the practicality and value of the method. Importantly, these alkenyl thiocyanates serve as valuable building blocks for the construction of diverse families of sulfur-containing molecules through trifluoromethylation, cycloaddition, oxidations, and C–S or C–P bond forming reactions.
Reversible Aminolysis: A New Concept for Postpolymerization Modification
Authors: Kasai Koki , Amii Hideki , Kakuchi Ryohei
Published: July 2024

Despite the powerful synthetic benefits of aminolysis postpolymerization modifications (PPMs), conventional aminolysis PPMs suffer from irreversibility owing to the difficulties in cleaving amide bonds formed from activated esters and amines. This occurs because conventional activated esters are chemically activated by enhancing the leaving group ability of alcohol residues. In this study, we propose a new aminolysis PPM system that enables reversible reactions by regenerating activated esters.

Published: July 2024

The development of novel polymer-based nanocomposites necessitates the experimental preparation and characterization of numerous compositions to identify optimal formulations. For thermoplastic-based materials, the compounding process typically involves the labor-intensive tasks of dispensing, weighing, mixing, and extruding solid components such as polymers and additives. Herein, we present an open hardware solution that aims to automate this process. Our setup system is designed to streamline material surveying tasks associated with experimental design or closed-loop, self-driving laboratories. Our hardware setup consists of two main components: a multi-material pellet dispenser, which simplifies the preparation of targeted compositions from a range of master batches, and a pellet collector-distributor, which efficiently gathers and distributes processed materials into various containers throughout the experiment.
Water splitting at imine-linked covalent organic frameworks
Authors: Gottwald Felizitas , Penschke Christopher , Saalfrank Peter
Published: July 2024

Covalent organic frameworks (COFs) are a promising class of metal- free catalysts, offering a high structural and functional variety. Here, we systematically study imine-linked COFs with donor (D) and ac- ceptor (A) groups using density functional theory (DFT). Using water splitting as a model reaction, we analyze the effects of protonation of the catalyst, the orientation of the imine linkage leading to differ- ent constitutional isomers, and solvation. In agreement with experi- mental results, we show that protonation decreases the band gap. In addition, COFs in which the donor is closer to the nitrogen atom of the imine group (DNCA) have lower band gaps than those in which the donor is closer to the carbon atom (DCNA). Three different D/A COFs are compared in this work, for which energies for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) and corresponding electrochemical overpotentials are computed. We show that reaction energies are very similar for DCNA and DNCA COFs. The differences in hydrogen evolution rates between the constitutional isomers observed experimentally in (photocatalytic) HER (Yang et al., Nature Commun. 13, 6317 (2022)), are proposed to be at least in part a consequence of differences in charge distribution.
Correcting Implicit Solvation at Metal/Water Interfaces Through the Incorporation of Competitive Water Adsorption
Authors: Lee Kwanpyung , Schmidt J. R.
Published: July 2024

Conventional continuum solvation models are ubiquitous in computational catalysis, including for describing metal/water interfaces which are relevant to both solution-phase heterogeneous catalysis and electrocatalysis. Nonetheless, we find that such continuum models qualitative fail to describe both the adsorption free energy and conformational preference for many organic molecules at such interfaces, largely due to the failure of continuum models to incorporate the role of competitive water adsorption. We develop a simple phenomenological model that accounts for competitive water adsorption and show that the model, when used in conjunction with continuum solvation, provides a dramatic improvement in the description of both adsorption and conformational preference. The model is also extended to additionally incorporate the influence of applied potential at the electrode surface, thus facilitating computationally efficient applications to scenarios including electrocatalysis.

Published: July 2024

The formation of novel complexes from so far non-investigated ligands and different metal centers is important for the development of new functional materials such as (photo)catalysts or biologically active compounds. Still, promising strategies to quickly and systematically investigate the complexation behavior of selected ligands are rare. We developed an NMR-based screening approach to monitor changes within reaction mixtures containing metals and ligands on a small scale via a simple but reliable protocol. Based on the obtained data, we could draw conclusions on the formation of 2-(1', 2', 3'-triazol-1'yl)quinoxaline-based transition metal complexes. The NMR screening results obtained were confirmed by the repetition of selected experiments on a large scale, and wherever possible, the type of complex obtained was evaluated by crystal structure elucidation. We could show the versatile complexation of the selected ligands with copper, gold, and silver in a bridging, chelating, or monodentate manner. The calculated theoretical properties supported the experimental results and enabled initial in silico predictions of similar compounds before conducting the complexation experiments and structural analyses.
Emerging Trends in Multi-Objective Optimization of Organic Synthesis Leveraging High-throughput Tools and Machine Learning Methods

Published: July 2024

The discovery of optimal conditions of chemical reactions is a labor-intensive, time-consuming task that requires exploring a high-dimensional parametric space. Historically the optimization of chemical reactions has been performed by manual experimentation guided by human intuition and Design of Experiments where one reaction variable is modified at any one time to find optimal conditions for one specific reaction outcome. Recently a change of paradigm in chemical reaction optimization procedures has been enabled by the advances in lab automation and the introduction of machine learning algorithms, where multiple reaction variables can be synchronously optimized to obtain optimal reaction conditions requiring a shorter amount of experimental time and minimal human intervention. Herein, we review the state-of-the-art of high-throughput automated chemical reaction platforms and machine learning algorithms that are currently used to drive the optimization of chemical reactions, highlighting the limitations and future opportunities that this new field of research encounters.

The Impact of Social Media on Business Performance of Women Entrepreneurs and their Empowerment: A Mixed Methods Study in the Context of Sri Lanka
Authors: De Silva Thilini , Hansson Henrik
Published: July 2024

The impact of social media on business performance of women entrepreneurs and their empowerment is examined in this research. Focusing on Sri Lanka, two research questions are addressed: (1) How are social media platforms empowering women entrepreneurs in Sri Lanka today, and (2) How can the use of social media be improved to support women entrepreneurs in Sri Lanka? A mixed-methods approach was used, with a survey (157 responses) and an online focus group (5 respondents)  discussion. The statistical findings showed that business performance of women entrepreneurs mediates the relationship between use of social media and women’s empowerment. Qualitative analysis revealed that the use of social media transforms mindsets, facilitates knowledge sharing, provides motivation, supports business operations, promotes gender-neutral branding, and enables networking for women entrepreneurs in Sri Lanka to enhance the performance of their businesses, leading to empowerment. To enhance support, social media platforms should prioritize motivation, targeted networking, professional courses, and robust security measures.
Método especulativo e atualidades vazias
Authors: Arnaut André
Published: July 2024

Neste artigo, defendo a ideia de que o método especulativo de Whitehead, em sua apropriação por Harman na forma do que chamarei de uma fidelidade aos híbridos, deve levar-nos, contra Whitehead, a uma metafísica que acolhe a noção de atualidades vazias. Mostro, assim, como as atualidades vazias da retirada dos objetos reais harmanianos podem por um lado, não recair no relacional e, por outro, não ser um mero nada a ser descartado. Nessa leitura da filosofia orientada a objetos de Harman, atualidades vazias estão envolvidas na expressão mesma das razões no irreducionismo de Harman, isto é, das razões enquanto híbridas ou weird.

Em afinidade com conceitos como só-depois, perspectivismo e sobrevivência, se indaga a suposta sucessividade de determinadas cadeias discursivas, introduzindo pelo ensejo da lógica anacrônica de um atlas as operações e as potencialidades de um fazer ficcional e das variadas formas de uma reunião. O argumento servirá para refletirmos sobre as possibilidades de compartilhar mundos por vir e compor alianças entre existências humanas e não-humanas na cosmologia da modernidade.
EPISTEMOLOGÍA Y ONTOLOGÍA
Authors: Plantamura Pilar
Published: July 2024

Las epistemologías crean mundos: una de las maneras en que lo hacen es a través de la perspectiva que toman las políticas públicas que definen el desarrollo económico y social de una región. Un ejemplo es la concepción de ambiente-territorio que en entre fines del siglo XIX y principios del siglo XX -cuando se consolidaba la constitución del l Estado Argentino-, se llevó a cabo presuponiendo una epistemología que negaba la existencia del otro y sus saberes (epistemicidio); siendo estos “otros”, naciones o territorios que no responden a las imágenes de lo que denominaremos el Norte Global. En este sentido, en el presente trabajo se analizará el caso de la introducción de la trucha arcoiris, a ejemplo de epistemicidio, a través de informes y diarios de viaje de científicos y naturalistas de fines del s.xix y principios del xx.

Este ensaio consiste no comentário a uma passagem do último capítulo de O pensamento selvagem. Ele procura elucidar o objetivo antropológico de “dissolver o homem”, propondo que, com isso, Lévi-Strauss empreende uma transformação cosmológica da antropologia. Trata-se de indicar a dimensão cosmopolítica do pensamento selvagem de Lévi-Strauss
LA PATERNIDAD INDISCUTIDA
Authors: Di Berardino María Aurelia
Published: July 2024

Es innegable que los distintos acercamientos cosmopolíticos (o emparentados) remiten a ciertos aspectos de la filosofía del psicólogo norteamericano William James. Por ejemplo, encontrarnos vínculos entre la referencia circulante que aparece en las cartografías que analiza Bruno Latour y la perspectiva inmanentista de James. Por otro lado, también, podemos seguir los múltiples análisis en los que Isabelle Stengers lo convoca para habilitar discusiones sobre pluriversos y opciones genuinas. O podemos reflexionar sobre las muchas evocaciones en las que la filosofía tentacular de Donna Haraway recupera la filosofía relacional jamesiana. En todos estos casos, hay un rastro plural que nos lleva a una paternidad que asumo indiscutida y que gira en torno a la metáfora del mosaico y sus múltiples derivas. Una de ellas y tal vez, la más oportuna, sea la reconsideración de que en esta inmanencia estamos todos/as comprometidos/as con el destino del mundo (o al menos, con el de un mundo).
¿QUÉ ES LO DECOLONIAL?
Authors: R. Magalhães Zé Antonio
Published: July 2024

Este articulo está basado en una ponencia de mismo nombre que presenté en el Coloquio Internacional Cosmopolíticas II – Primaveras cosmopolíticas, en 2020. En él, propongo un sentido posible para el concepto de lo decolonial. Este sentido de lo decolonial se produce estableciendo un paralelo entre el giro, en la teoría contemporánea, del posestructuralismo/deconstrucción a las teorías especulativas (realismo especulativo, giro ontológico, nuevos materialismos etc.), y un posible giro análogo, en los estudios de la colonialidad, de un poscolonialismo epistemológico/desconstructivo, vinculado a la crítica del saber/poder colonial, a una ontología/metafísica decolonial preocupada conanimar pensamientos no-occidentales y no-modernos. En contraste a la crítica interna de la modernidad/colonialidade, o de la descubierta de epistemologías no-modernas, se sugiere una “descolonización del pensamiento” a través de la coproducciónde ontologías/metafísicas decoloniales.
Desajustados da Floresta
Authors: Brulon Bruno
Published: July 2024

Adotando a indisciplina como ponto de vista para observar museus e exposições, este artigo analisa a exposição Queermuseu: cartografias da diferença na arte brasileira, cuja censura em 2017 levou a um movimento no Rio de Janeiro pela sua abertura na Escola de Artes Visuais do Parque Lage, entre agosto e setembro de 2018. Nossa análise se baseia no potencial de insubordinação de uma exposição que se tornou um devir do socio-ativismo museal no contexto político brasileiro nos anos que antecederam Ã  eleição do presidente Jair Bolsonaro. Com base na análise etnográfica da exposição e do programa educativo da EAV, buscamos compreender as disputas de narrativa sobre o “queer” e o “normal” ou o “ajustado”, denunciando a violência museal sobre os corpos dissidentes e discutindo as apropriações contemporâneas dos museus em sua insubordinação ao poder disciplinar.
MANAGING POSTNORMAL COMPLEXITY, CHAOS, AND CONTRADICTIONS WITH THE MUSLIM MINDSET (Interview with Shamim Mia)
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Muzykina Yelena
Published: July 2024

There are different definitions of modernity. One calls the present “postnormal times” or “an in-be-tween period when old orthodoxies are dying, new ones have yet to be born, and very few things seem to make sense.” This definition appeared in 2010 in Welcome to Postnormal Times, a seminal paper by Ziauddin Sardar, a British Muslim polymath. This concept structured the interview with Dr. Shamim Mia (London, UK). During the conversation, he examined issues of modern social life from the Muslim world-view perspective in the context of postnormal times (PNT). The interview offers an analysis of the key characteristics of PNT – complexity, chaos, and contradictions – and their examples in contemporary Muslim communities. The discussion also addressed the separation of Islamic Studies from Muslim Stud-ies in modern academic science. It would help raise awareness and correct conclusions regarding several pressing issues related to modern Islam and those who profess it. The interview also briefly touches upon political Islam, its place and role in a modern developed society, as well as the need to nurture critical thinking among those who profess Islam.

Some aspects of increasing the efficiency of noctilucent clouds ground-based observations are considered. The study of such objects is highly relevant in connection with the general problems of climate change. It is shown that the limitations on the possibility of registering the phenomenon in the optical range are associated both with the relatively low brightness of clouds of this type against the background of the twilight segment, and with the strong absorption of light by dust aerosol in the surface layer of the atmosphere. The paper substantiates the idea that the transition to observations of noctilucent clouds in the near infrared range will increase the contrast of their images in the twilight segment. This will make it possible to detect noctilucent clouds during civil twilight, including at low altitudes above the horizon. To test this assumption, shooting was carried out during the 2022 season using a CANON 2000 D camera and RG780 and RG830 infrared filters. The images revealed features morphologically similar to noctilucent clouds. An analysis of the images showed that they can hardly be associated with tropospheric clouds or anthropogenic formations. The results obtained were compared with ground-based observation data from other points, as well as with satellite information on the state of noctilucent cloud fields. This comparison showed that noctilucent clouds, which were not detected in visible light images, were highly likely to be detected in near-infrared images. The prospects for the application and development of the proposed method for ground-based registration of noctilucent clouds are also considered.

Wireless Mesh Networks (WMNs) remain pivotal in various domains due to their versatility and scalability, offering robust and adaptable connectivity in areas where traditional wired networks are impractical. They find extensive use in diverse scenarios like smart cities, disaster recovery, industrial automation, and rural connectivity, underscoring their continued relevance in modern networking applications. Recent research in WMNs has increasingly concentrated on optimizing gateway placement and selection to enhance network performance and ensure efficient data transmission. This paper introduces a novel approach to maximize average throughput by strategically positioning gateways within the mesh topology. Leveraging Coulomb's law, previously employed in network analysis by Zhang et al., this method aims to enhance network performance through optimized gateway placement. Through thorough simulations and analysis, the effectiveness of this approach in improving both throughput and network efficiency is demonstrated. This study contributes to the ongoing evolution of WMN optimization strategies, emphasizing the indispensable role of gateway placement in establishing robust and efficient wireless communication infrastructures. By leveraging physics-based models like Coulomb's law, the proposed approach provides a framework for objectively optimizing gateway placement, thereby addressing a critical aspect of WMN design. These findings offer valuable insights for network designers and operators, guiding informed decision-making processes for gateway deployment in diverse WMN deployments.
LES modeling gas particle dispersion and thermal characteristics in a reacting turbulent low
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Rutkuniene Zivile
Published: July 2024

This paper presents the results of a 3D computer simulation of the combustion processes of gas particles (methane) in turbulent flow by applying numerical methods for calculating complex turbulent flows. The numerical model for calculating turbulent reacting flow is based on the filtered equations of conservation of mass, momentum, and internal energy using a spatial filter for calculating and modeling complex vortex structures. Aerodynamic, temperature and thermal characteristics of the flow were obtained based on the study on the influence of the Sauter mean radius of methane particles on its distribution and combustion processes. 3D visualization of the reacting flow was obtained considering the degree of its turbulence and the intensity of methane particle collision on the area of its distribution. The obtained results can be used for a deep understanding of the theory of gas combustion, in combustion chambers of various thermophysical objects and as an alternative to liquid hydrocarbon fuels due to safety and low harmful load of methane on the environment.
