Outbreaks of airborne infections during meal consumption in diverse restaurant settings have been extensively reported. It is widely recognized that effective ventilation strategies are essential to minimize the infection risk indoor environments, and these should be tailored heat sources. The purpose this study compare spatial distribution rooms use mixing or displacement ventilation, specifically focusing on sources used for different food types, namely hotpot, normal Chinese food, iced...
Euler-Lagrangian numerical simulation framework of gas-solid two-phase flow was used to simulate the characteristic in fibrous media using OpenFOAM this study. The results were compared with empirical model and CFD-DEM method. In addition, deposition morphology particles, pressure differential filtration efficiency unsteady stage cost also analysed OpenFOAM. show that can process media, particles are agglomerated on surface form a dendritic structure similar experimental observation. would...
Fine dust is one of the important factors affecting precision instruments and human health, pleated filter media has been widely used in air filtration field. Based on SEM image actual media, a microscopic 3D model was established gas–solid two-phase flow simulated using OpenFOAM. The results show that OpenFOAM can well simulate particle deposition surface fibre dendritic structures. transverse distribution amount deposited form two peaks structure, while longitudinal distributions 30° 60°...
The crystalline solid-air in the liquid hydrogen will cause erosion or friction on elbow, which is directly related to safety of transportation. CFD-DPM model was used study characteristics pipelines. Results show that outer wall cryogenic elbow has serious range 60–90°, different from general elbow. rate linearly positively correlated with mass flow particles, and a power function relationship rate. fitted curve can be predict erosion. structure also an important influence solid-cavity...
In superconducting system, current lead connecting cryogenic device and normal temperature copper cable is the main leakage heat source of entire system. Its performance directly affects cooling cost Multi-current leads have advantages eliminating Joule reducing conduction leakage. As a commonly material, MgB <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> (magnesium diboride) has broad application prospects. this paper, 200 A are...
Abstract Liquid hydrogen is an important way for energy storage and transportation in the future. However, safety issue should be a concern because it will quickly form low- temperature, flammable explosive vapor cloud when liquid leaks. A new helium spill experiment method was used to predict dispersion characteristics of confined space at this work. The concentration infrared images near pool were obtained same time. Results show safe reliable study leakage diffusion instead helium. After...
The leakage of hydrogen in a room is key issue safety, and ventilation plays an important role dispersion. usually builds thermal stratification environment due to the low temperature liquid or throttling effect. This study attempts develop fast-computational theoretical model dispersion motion indoor based on classical buoyant jet carry out experimental verify model. research results show that developed can well predict trajectory slowly releasing leakage. leak oscillates thermally...
Abstract The purpose of this work is to research the spill and diffusion characteristics liquid hydrogen in confined cabin with air supplying vent. behavior vent was simulated using Fluent software. feasibility model verified by experimental results. results show that numerical simulation can simulate predict process well has application value for engineering. cloud after gathering at top slowly spread surrounding which different from open environment. be divided into three stages, among...
Cryogenic liquefaction energy storage is an important form of for sustainable liquid hydrogen and other gases. The weighting parameter A in the parameter-adjusted two-phase LBM model deviation simulation results. aim this paper to discover appropriate eliminate deviation, solve problem large between theoretical solution simulated value that caused by using different equations state simulation. modified PT equation state, which suitable cryogenic fluids, combined with parameter-adjustable...
