Particle agglomeration is a common phenomenon in natural and industrial environments. This study investigates the motion characteristics of bidisperse agglomerates Stokes flow introduces novel drag model that explicitly incorporates particle number size ratio as critical parameters. By analyzing effects agglomerate structure, number, on settling behavior force, we demonstrate orientation determined solely by geometric while force primarily influenced ratio, with minimal impact from...
Size-based particle filtration has become indispensable in numerous biomedical and environmental applications. In this study, bioinspired by the filter-feeding mechanism (lobe filtration) of manta rays, we designed a U-shaped biomimetic gill rake filter that combined lobe Dean flow to monodisperse suspensions, bi-disperse suspensions yeast cells. Compared with other equipment using inertial focusing technology, our can perform high-throughput (up 8 mL min
Thermal performance of energy systems can be improved by adding metal or metal-oxide nanoparticles to a base fluid, thereby increasing heat-transfer efficiency. Laminar pipe flow Cu–water nanofluid was studied using discrete phase model numerical simulation and experimental methods. The forces including thermophoretic Brownian were considered solve the particles governing equation. A two-step method employed in preparation nanofluid. influences Reynolds number, fluid temperature, particle...
Aerosol nanoparticle deposition onto a surface under temperature gradient is commonly applied in the chemical and medical industries. In this study, numerical investigation with two-phase model used to investigate characteristics of nanosized particles 90° square bend. The effects variations gas phase physical parameters, such as density, viscosity, thermal diffusivity changing temperatures are studied. main forces acting on drag forces, Brownian thermophoretic forces. A discrete (DPM) based...
Bubble transportation and related flotation are ubiquitous phenomena in nature industry. Various surfaces with distinct morphologies specific wettability properties have been engineered by organisms humans to facilitate the targeted movement of bubbles. However, existing methods predominantly rely on continuous surfaces, limiting ability bubbles deviate from their path before reaching intended destination. Therefore, directional using noncontiguous still remains a significant challenge....
Bubble collapse near the liquid-liquid interface was experimentally studied in this paper, and dynamic evolution of a laser-induced bubble (generation, expansion, collapse) (dent rebound) were captured by high-speed shadowgraph system. The effect dimensionless distance between on direction liquid jet, migration, dynamics discussed. results show that: (1) jet generated during always directs toward denser fluid; (2) collapses penetrate when is close to interface; (3) three different shapes...
The blending of hydrogen gas into natural pipelines is an effective way achieving the goal carbon neutrality. Due to large differences in calorific values from different sources, value after mixing with may not meet quality requirements gas, and entering long-distance urban also has requirements. Therefore, it necessary study effect multiple sources pipe network types on following admixing. In this regard, aimed determine proportions hydrogen-mixed at home abroad, systematically determined...
A large number of molecules are usually required to model atomic walls in molecular dynamics simulations. virtual-wall is proposed this study describe fluid-wall interactions, for reducing the computational time. The infinite repetition unit cell structures within wall causes periodicity force acting on a fluid molecule from molecules. This first calculated and then stored memory. appearing field subjected can be determined by position relative wall. avoids excessive calculations...
There are various bubble cavitation phenomena in daily production and life, near-wall is the most common one. This paper studies dynamics between a rigid wall an elastic wall, by changing distance two walls initial position of bubble, several different collapse patterns obtained. Then, we discuss changes migration distance, gravity, maximum radius during cavitation. Finally, numerical simulation used to successfully acquire satellite bubbles appearing process which good agreement with...
The active control of two side-by-side cylinder wakes by tangential jets with a Reynolds number 3900 and pitch ratio 1.1 was studied experimentally numerically. particle image velocimetry technique used to obtain the flow around cylinders in wind tunnel, dynamic lift on measured three-axis force-sensor. A numerical model set up for comparison experimental data. effects jet angles intensities wake were discussed. It found that structure bistable biased gap led an asymmetry field. Tangential...
