Built up numerical simulation model of ufad system with single heat and pollutant source , adopted fluent software to study distribution of temperature 、 velocity and contamination ’ concentration , and changes of heat lamination height when temperature and velocity of air - in and surface temperature of heat source were changed and when the leakage of air - in plenum was considered or not . and compared and verified the simulation results with experimental testing data 建立了单一热污染源地板送风的数值模拟模型,采用fluent软件研究送风温度、送风速度、热源表面温度的变化及有无考虑送风静压层的漏风时,室内温度、速度和污染物浓度分布以及热力分层高度的变化,并与实测分析进行了对比验证。
To investigate effect of plenum chamber total pressure on arcjet thruster operation , numerical simulation of operation under various plenum chamber total pressures was performed on the basis of mechanism analysis on its operation and modeling for chemical non - equilibrium flow and steady state electromagnetic field within it 摘要为了研究集气腔总压对电弧喷射推力器工作过程的影响，在分析其工作机理的基础上采用化学非平衡流动和稳态电磁流体电磁场模型对不同集气腔总压下推力器工作过程进行了数值模拟。
