Dynamic Interferometry With Retrace Error Correction Using Fringe Projection For High-Gradient Fields
Authors: Psota Pavel , Lédl Vít , Dolecek Roman , Matoušek Ondrej , Stašík M.
Published: July 2024

This paper introduces an innovative approach aimed at advancing the characterization of high-gradient flow fields through the integration of dynamic interferometry and fringe projection techniques. Traditional interferometry offers a precise tool sensitive to optical path changes, typically used to measure refractive index variations induced by factors such as density changes in fluid flow. Rays are usually considered as straight lines, and refraction can be neglected. However, in scenarios involving high-gradient fields, such as supersonic flow with shock waves, optical path changes due to ray bending become significant. In these high-gradient fields, the trajectory of the ray is altered, leading to longer optical paths (resulting in incorrect values) and geometric distortions of the image (resulting in inaccuracies in position). Although retrace error corrections using numerical models of refractive index distribution can mitigate some effects, complete compensation is often challenging. To address this, our proposed technique integrates fringe projection, which is highly sensitive to ray deflections caused by variations in the index of refraction within a transparent medium. The method involves projecting a precisely defined multiplexed cosine fringe pattern across the measured area. Modifications in the pattern indicate ray bending, providing data for interferometric corrections. Real-time interferometry is seamlessly combined with the fringe projection technique to compensate for optical path length changes and mitigate mapping errors induced by ray deflections. The dynamic nature of this combined approach enables the instantaneous capture of both interferometric and fringe-projection data, making it a suitable tool for real-time measurements. Experimental verification of the technique demonstrates its efficacy, with a comparative study against traditional interferometry showcasing a significant reduction in mapping errors.

Published: July 2024

The motion and particularly the detachment mechanism of sessile drops in an air-shear-flow is highly relevant for many technical applications. For instance, water drops in fuel cells can block the oxygen transport and thus lower the overall efficiency. Hence, a deeper understanding of the drop detachment mechanism could facilitate efficiency optimisations. Nonetheless, until now only simplified models exist for predicting the critical velocity that do not take into account the mutual interaction of the air and the liquid via the non-rigid interface. One reason for this is the lack of knowledge of the flow inside the oscillating drop. In this contribution, we present the first three-dimensional flow measurements in oscillating sessile drops in shear flow. Time-averaged flow measurements were conducted for different Reynolds numbers. Furthermore, the phase-averaged flow field was measured. The measurements were conducted with a novel 3D-PTV method, which offers scanless three-dimensional flow measurements with a single optical access for a measurement volume that covers about 90 % of the drop volume. Moreover, we present a novel technique for conducting flow measurements through fluctuating gas-liquid interfaces based on adaptive optics. We demonstrate that this technique enables the correction of a systematic error corresponding to the magnitude of the first drop eigenfrequency, which seems to play an important role in the detachment mechanism of drops. The results give new insights about the fluid mechanics of sessile drops and thus may help in the optimisation of drop removal in e. g. fuel cells.

Published: July 2024

This study focuses on the development of a new laser diagnostic based on Laser Induced Fluorescence by seeding the gas (N2) in which hydrogen is injected with fluorescent tracer. In this paper, three tracers were characterized, two aromatic compounds (toluene and difluorobenzene) and one ketone (acetone). The first part of this study compared the fluorescence of both aromatic compounds without injecting H2 . More particularly the influence of a temperature variation on the quantum yield and cross section absorption was regarded. It appeared that difluorobenzene was more suitable LIF measurement than toluene as it has a higher quantum yield that is less dependent to temperature variation. Then, Negative LIF was tested using two different tracers (difluorobenzene and acetone) and considering three different post-processing methods to consider the temperature variation inside the hydrogen jet: no temperature correction, temperature calculated based on a CFD RANS simulation, temperature calculated via an isentropic expansion and adiabatic mixture hypothesis. Results evidence that the first and the third methods presents respectively a lower and upper limit for the hydrogen mole fraction when the second method is biased by the presence of shock and expansion structures near the injector nozzle. Finally, it appears that, with the proper temperature correction, difluorobenzene and acetone yield similar results, despite the fact the acetone fluorescence needing more amplification to be captured, the signal to noise ratio is lower than for aromatic compounds.
Comparison Of Full-Scale PIV Measurements With CFD Simulations Of A Ship Propeller Inflow

Published: July 2024

Flow around the ship's hull and specifically the inflow conditions of the propeller(s) critically influence the propeller efficiency and cavitation behaviour. In a typical single-propeller vessel, the hull of the ship creates a velocity deficit in the top part of the propeller disk. This creates suitable conditions for cavitation, which is the main source of noise and vibration both inside the vessel as well as in the marine environment. Recently, two measurement campaigns were performed using a novel full-scale stereo-PIV device built to measure flows around vessels sailing at sea. During the first campaign, performed in one of MARIN's basins, the device was commissioned. The second campaign was performed during a sea trial; it resulted in propeller inflow data that can be used for validating CFD codes. The uncertainty of the PIV measurements was assessed using both campaigns. In the basin, uncertainty bias could be determined by comparing the PIV results with the carriage speed. At sea, the random part of uncertainty was determined by quantifying the standard deviation of the mean velocity for all three velocity components in the wake peak area of the propeller inflow. Overall, the uncertainty was found to be acceptably small, given the scale of the measurement and the necessity to work with naturally occurring seeding particles in the sea. CFD calculations of the same full-scale flow were performed using an in-house flow solver. The CFD results predicted the propeller RPM and the delivered power measured during the full-scale trial well, which gives confidence in the ability of CFD to predict ship trial performance. The comparison of the flow fields was good, with the PIV results demonstrating that full-scale PIV can be done reliably, and that the CFD is able to capture the major features of the flow in the considered area. For a large part of the flow field, the CFD was within the measurement uncertainty band. The wake peak was slightly underpredicted, which may be related to roughness effects on the boundary layer thickness.
Comparative Analysis Of Brightness-Based Laser-Induced Fluorescence (BBLIF) And Structured Planar Laser-Induced Fluorescence (S-PLIF) For Film Thickness Measurement In Two-Phase Flow
Authors: Sherif Ahmed Abou , Johnson Kathy , Hann David
Published: July 2024

Improved understanding of the interactions between gas and liquid phases in gas sheared film flow is crucial for n improved capability to employ computational modelling in the future to optimize systems, thereby reducing environmental impact, increasing efficiency, and enhancing productivity. This abstract compares two techniques for measuring the thickness of the film in different regimes visible in a rectangular cross-section gas-sheared liquid film rig, namely previously published Brightness Based Laser Induced Fluorescence (BBLIF) data and Structured Planar Laser Induced Fluorescence (S-PLIF) from the current investigation. The study presents and compares examples at a specific liquid flow rate (8 litres per minute) for superficial gas velocities in the range 1 m/s to 10 m/s, noted as being in different flow regimes. The investigation reveals that the S-PLIF technique produces results that are within the uncertainty bands of the BBLIF data for most scenarios. However, in the transition regime, statistical variations emerge. The frequency content of the two film heights is analyzed using a Hilbert-Huang Technique. This shows clearer results for the S-PLIF than for BBLIF which is attributed to the erratic values that can occur in BBLIF when total internal reflection occurs. It is concluded that the S-PLIF technique demonstrates promise as a reliable method for determining film thickness which is highly advantageous as it can be applied to images obtained with seeded flow intended for PIV analysis. The S-PLIF film thickness data can be used for generating automated masks for PIV analysis concurrently conducted in both the gas and liquid phases. This advancement facilitates the enhanced capability to advance understanding of complex fluid dynamics and optimize system performance.
A Meshless Method To Compute The POD And Its Variants From Scattered Data
Authors: Tirelli Iacopo , Mendez Miguel Alfonso , Ianiro Andrea , Discetti Stefano
Published: July 2024

The Proper Orthogonal Decomposition (POD) is one of the most popular methods for discovering patterns from data in fluid mechanics. When the data is available on a uniform grid, such as in cross-correlation-based particle image velocimetry, the POD is equivalent to a Singular Value Decomposition (SVD) of the matrix containing the measurement. When the data is scattered, as in particle tracking velocimetry, the POD computation first requires interpolation onto a grid. Such interpolation degrades spatial resolution and limits the benefits of PTV over correlation-based methods. In this work, we propose a method to compute the POD from scattered data that circumvents the need for interpolation. The method uses physics-constrained Radial Basis Function (RBFs) regression to compute inner products in space and time. We demonstrate that this method is more accurate than the traditional interpolation or binning-based approaches. Since the method does not require the definition of a mesh and produces results that are analytic and mesh-independent, we refer to our method as meshless POD.
Light Reflections Detection And Correction For Robotic Volumetric PIV

Published: July 2024

Laser light reflection mitigation in Particle Image Velocimetry (PIV) is crucial for accurate flow field measurements. While numerous methods exist for planar PIV, fewer have been developed for volumetric PIV systems, and in particular for coaxial setups like robotic volumetric PIV. Light reflections in volumetric PIV experiments result in high-intensity regions that corrupt particle detection and analysis. This study presents a novel approach for treating light reflections in robotic volumetric PIV experiments. The proposed method uses image filtering and masking techniques in the wavenumber space to separate particle images from reflection regions. The process involves decomposing the image signal into low- and high-wavenumber components using the 2D discrete Fourier transform (DFT) to then use a high-pass filter to attenuate the intensity of the reflection regions. Finally, a step of automated adaptive masking is applied to remove residual reflection areas that the filtering is not able to eliminate. The proposed approach is tested on experimental data obtained from experiments performed using robotic volumetric PIV on two different geometries: a side-view mirror and a rotating two-blade propeller. Comparison between raw and pre-processed images, as well as particle tracking results, is presented. The results from this data comparison show successful removal of reflection-induced artifacts in instantaneous images by using the spatial Fourier filter automated masking approach. The developed image pre-processing strategy effectively removes unsteady light reflection regions in robotic volumetric PIV images, preventing the appearance of spurious particle tracks and improving the accuracy of flow field measurements. The spatial gaps introduced by the masking procedure can be easily filled in via measurements from multiple directions, which are promptly achieved via the robotic volumetric PIV approach.
Volumetric Measurements Of Particle-Wake Interactions
Authors: Tee Yi Hui , Dawson James R. , Hearst R. Jason
Published: July 2024

Research on freely falling particles has primarily focused on wake dynamics and vortex shedding of individual particles in quiescent flow. When these particles fall collectively, the wakes of surrounding particles alter the flow fields. Hence, we conducted volumetric experiments to investigate how the settling and wake dynamics of particles are affected by the wakes of other settling particles. Negatively buoyant 12 mm particles of (sphere, flat cuboid, circular and square cylinders) are first released individually into quiescent water. Then, the particles are released individually into the bulk wakes of 20 mono-dispersed particles. Using four high-speed cameras and LEDs, we simultaneously capture both 3D particle and fluid motions in the terminal velocity regime. The imaging domain measures 90 mm x 90 mm x 40 mm. Our results show that all trailing particles settling through the bulk wakes gain additional downward momentum from the turbulent wakes, falling faster than in the quiescent flow. Upstream of the particle, the vortices in the bulk wake interact with the developing shear layer along the particle. The wake downstream of the trailing particle also appears more chaotic than that in a quiescent flow.

Published: July 2024

The detrimental effects of gasoline-powered vehicles on both the environment and human health have prompted the automotive industry to shift towards electric vehicles (EVs). This report aims to explain the functioning of an electric vehicle and compare it to both internal combustion engines (ICEs) and hybrid vehicles. Additionally, it explores the advantages and disadvantages of EVs, along with a glimpse into the future of this technology. EVs are significantly more efficient than ICEs, converting a higher percentage of energy from the grid to power the wheels. They also offer instant torque, providing quick acceleration and a smoother driving experience. While they may have limitations such as limited range and higher upfront costs, the numerous benefits they provide in terms of sustainability, efficiency, and reduced emissions make them a viable alternative to conventional gasoline-powered vehicles.

Authors: Dittakavi Raghava Satya SaiKrishna
Published: July 2024

In the context of modern computing landscapes marked by escalating resource demands and cost considerations, this paper introduces a novel framework that integrates artificial intelligence (AI) for the creation of resource-efficient applications while maintaining a keen awareness of costs. The imperative to strike a harmonious equilibrium between application performance and expenses has never been more pressing, especially with the proliferation of cloud-based services. In response, our approach capitalizes on AI methodologies to dynamically analyze real-time application requisites, workload trends, and the availability of resources. Central to our methodology is the elevation of cost to a principal design determinant. We devise strategies that dynamically apportion resources, opt for suitable service tiers, and make necessary adjustments to application configurations. This duality of optimizing performance while curtailing expenditure underscores the essence of our approach. Rigorous simulations and empirical evaluations underscore the efficacy of our strategies across diverse scenarios, underscoring substantial cost reductions without compromising the quality of applications.

Published: July 2024

O escoamento corpóreo é responsável pelo transporte de substâncias significativas para o funcionamento do corpo humano e seu entendimento é importante para a medicina justificar algumas doenças. Com intuito de contribuir, a engenharia busca compreender os fenômenos físicos envolvidos por meio de análise fluidodinâmica. Este trabalho tem como objetivo desenvolver um estudo preliminar de um modelo de fluxo sanguíneo utilizando técnicas de Fluidodinâmica Computacional (CFD), avaliando a eficácia de dois modelos: modelo constante e modelo de Casson. Foram realizadas simulações no software ANSYS CFX 19.1 utilizando dois modelos introdutórios sobre a hemodinâmica. O primeiro modelo considera as especificidades constantes do sangue, enquanto o segundo utiliza o modelo de Casson, que apresenta uma variação dependendo da taxa de cisalhamento. Os resultados obtidos das simulações indicam que a malha utilizada nas análises precisa ser refinada para melhorar a precisão dos dados. As variações na tensão de cisalhamento e na distribuição da particularidade entre os dois modelos sugerem diferenças importantes que devem ser consideradas em estudos futuros. Conclui-se que, embora os modelos utilizados tenham fornecido uma base inicial para o estudo do fluxo sanguíneo, é necessário aprimorar a malha das simulações computacionais para aumentar a precisão dos resultados. Este aprimoramento permitirá uma melhor compreensão das informações hemodinâmicas e poderá contribuir para estudos mais avançados e aplicações clínicas.

O objetivo do corrente artigo é verificar a mudança de atuação do Ministério Público no âmbito criminal a partir da resolutividade. Em outras palavras, a pretensão deste artigo equivale a diagnosticar se haveria um direito fundamental a uma atuação ministerial resolutiva dentro da ótica penal, diferenciando-a do ramo cível. Sem prejuízo, constitui aqui como pretensão secundária trazer exemplos dessa mudança de paradigmas e o impacto disso, o que denota a importância da temática aqui abordada. A pesquisa é de natureza bibliográfica e documental e o método utilizado é o dedutivo. Parte-se, então, da premissa genérica, analisando a existência ou não de um direito fundamental à atuação ministerial resolutiva na esfera criminal, diferenciando-a de outros setores. A partir disso, adentra-se a exemplos de instrumentos da resolutividade ministerial e os cenários e impactos dessa mudança. Conclui-se que, atualmente, a partir das mudanças legislativas e de entendimento do agir ministerial, alinha-se plenamente à existência de um direito fundamental à atuação resolutiva ministerial, como compromisso de eficiência e em observância ao direito fundamental à razoável duração do processo ou procedimento. Nesse contexto, podem ser mencionados como exemplos não somente institutos despenalizadores, mas também entendimentos no impulsionamento das investigações criminais e no exercício do próprio controle externo da atividade policial. O referencial teórico utilizado é a Análise Econômica do Direito e a Teoria do Agir Comunicativo habermasiana.

Learning from risk: an ethnography of a risky play
Authors: Coelho Luciano Silveira
Published: July 2024

This text discusses the relationship between risk and learning in the practice of the rolling cart, based on an ethnography carried out in the metropolitan region of Belo Horizonte between 2019 and 2022. The community involved in the activity is characterized by disputes and interests about this practice. Although it is considered risky, different narratives about the risks of this practice emerge in an urban and contemporary context. The analysis presented argues that risk is a social construction, in line with Jean Lave's theories of situated learning and Tim Ingold's ecological approach. According to these theories, the skills necessary to practice rolling cart are developed through a process of education of attention, and not through mental representations that are converted into body movements. Thus, men, women, adults and children participate, constitute and are constituted by the practice, which is polysemic and situated. The theories of Giddens and Douglas are also relevant to the discussion, as they suggest the social construction of risk and the importance of the cultural and social context in which this practice is carried out. In short, the analysis emphasizes the complexity of the relationship between risk and learning in rolling cart practice and the importance of considering the ecological approach to understand the dynamics of this community of practice.

O Brasil é o maior produtor e exportador de Soja no mundo. Na última safra 2022/2023 o país alcançou recorde de produção com 150,36 milhões de toneladas do grão, sendo  o Estado  Paraná responsável por 22,37 milhões de toneladas. Diante disso, para que a produtividade seja sempre maior pós-safra, é necessário a utilização de tecnologias que irão evitar possíveis perdas. A convivência da cultura da soja com as plantas daninhas reduz a produção. Atualmente, evitar a competição é um desafio para os sojicultores. Herbicidas pré-emergentes são fundamentais nesse sentido. Assim, o objetivo do presente trabalho foi analisar a eficiência no controle de plantas daninhas com o uso de diferentes herbicidas pré-emergentes na cultura da soja, bem como, os seus componentes agronômicos no município de Jardim Alegre. Foram utilizados os produtos com nome comercial de Zapp® em combinação com os produtos Paxeo®, Spider®, 2,4-D® Zethamaxx®. Para os tratamentos padrões foram usadas a testemunha (livre de produto) e a testemunha capinada.  Foram avaliadas as características eficiência de controle, produtividade, emergência de plântulas, inserção de primeira vagem, estande, altura de planta, número de vagens e números de sacas. Os resultados encontrados foram que a combinação de glifosato com diclosulam/halauxifeno metílico reduziram a emergência de plântulas, provavelmente devido ao halauxifeno metílico. A altura da primeira vagem e das plantas foi afetada pelas combinações de herbicidas, impactando a colheita mecanizada. Logo, o número de vagens aumentou com glifosato/imazethapyr/flumioxazin, mas afetando significativamente a produtividade. No geral, a produtividade foi consistente com a média nacional, não sendo influenciada pelo controle de plantas daninhas, em decorrência de condições climáticas favoráveis ao desenvolvimento da cultura.

A Educação Escolar Indígena é uma modalidade da educação básica que garante aos indígenas, suas comunidades e povos a recuperação de suas memórias históricas, reafirmação de suas identidades étnicas, a valorização de suas línguas e ciências, bem como o acesso às informações, conhecimentos técnicos e científicos da sociedade nacional e demais sociedades indígenas e não-índias. Nesse contexto, a Educação Escolar Indígena é assegurada na Constituição Federal Brasileira de 1988, na Lei de Diretrizes e Bases da Educação Nacional (Lei 9.394/96) que garante às comunidades indígenas o direito à educação diferenciada, específica e bilíngue. Esse artigo busca compreender os principais avanços e dificuldades na implantação da proposta escolar indígena diferenciada no espaço de uma escola indígena da região Serra da Lua- Roraima através da percepção de coordenadores pedagógicos e professores. Trata-se de uma pesquisa qualitativa, tendo como instrumento de coleta de dados a realização de questionário. Os resultados indicam que é fundamental que o trabalho de aplicabilidade da educação diferenciada seja feito em parceria com os povos indígenas.

The survey was conducted on 842 professional soldiers working in the Army Capital Corps, and soldiers living in BOQ(Bachelor Officers Quarter) were divided into MZ-generation soldiers and older-generation soldiers.
First, in terms of accessibility and community factors, the MZ generation tended to have fewer complaints than the older generation. This reflects the characteristics of the 'digital nomad' MZ generation. Second, the two-track policy that discriminates against married and unmarried executives should be improved. Third, it is necessary to promote a policy of customized support for military housing for the MZ generation. Due to the nature of the MZ generation, which likes to live alone in a space, it seems necessary to expand personal space and integrate common facilities such as washing machines and dryers. Fourth, total home care services are needed. For MZ-generation soldiers, it is necessary to support all accommodation cleaning, laundry etc.
In the future, the MZ generation will become the main personnel of the military administration, and innovative military housing policies should be reflected in consideration of the characteristics of these MZ generations.

The basic principles of the Constitution are stipulated in Article 12 of the Constitution so that they can be implemented in practice through the Criminal Procedure Act. These include the basic principles of criminal procedures, such as the due process principle, warrant principle, prohibition of torture and coercion of unfavorable statements, the law of exclusion of confession and the law of reinforcement of confession, and the notification and notification system of reasons for detention, etc. However, the Japanese police tortured Yu Gwan-sun severely, including hanging her from the ceiling. At the time of his arrest, the stab wound to his side had not been treated and the flesh had rotted away to the point that his hands were bloody. Due to daily beatings, untreated wounds, beatings, and long-term torture, his bladder ruptured and his body deteriorated. Due to the back wound he received in the Manse Movement and the beatings and torture in prison, his bladder ruptured and his body rotted, but he was still considered a felon. The prison’s treatment of him without treatment was the deciding factor that ended his short life. https://namu.wiki (Namu Wiki).
It may be a bit difficult to consider the reality at that time in the current legal system, but if you look at it from a historical and criminal law perspective, it is clear that harsh treatment during the investigation process stipulated in criminal procedures and confessions made in illegal circumstances did not serve as evidence of guilt. In addition, the fact that a confession cannot be used as evidence of guilt and punished when it is the only evidence against the defendant was not observed, even though it must be observed to guarantee the right to defense of the suspect and the accused. As mentioned above, I had an indirect experience of violation of basic rights through the death of martyr Yu Gwan-sun. We should not forget that, like martyr Yu Gwan-sun, he was tortured without being guaranteed his basic rights and unable to fully exercise his right to defense as a party. Ji-Hyeon Kang, Hae-Won Kim, Public Law Studies, Volume 22, No. 1, February 2021.
In the end, it appears that the Japanese police’s torture of martyr Yu Gwan-sun violated Article 12, Paragraph 1 of the Constitution and Article 309 of the Criminal Procedure Act under the current law. It is presumed that the torture of Yu Gwan-sun at that time involved harsh acts such as an all-night investigation and verbal abuse. This violated human dignity, value, and the right to pursue happiness, and an unfair sentence was imposed due to false confessions through assault and harsh acts during the investigation. It is clear that he received . Acts such as torture constitute illegal acts and there is an obligation to compensate for damages. As explained above, it is clear that the Japanese police violated the ban on torture and violated the constitutional provisions guaranteeing the right to refuse to make statements.
