利用FDS软件预示风口布置对热舒适性的影响

Predicting the Influence of Different Ventilation Arrangements on Thermal Comfort through FDS

本文以NIST开发的FDS程序为平台,采用LES方法对室内气流组织情况进行了数值模拟,对不同气流组织条件下的舒适性进行评价。主要完成了不同风口布置形式下室内的气流组织模拟,运用舒适性评价方法对采集到的数据进行了计算,分析和比对了风口布置对热舒适性的影响。

Based on the advanced Computational Fluid Dynamics package Fire Dynamics Simulator released by the National Institute of Standards and Technology in the U.S.A., the circumstance of the indoor air distribution is simulated and studied by the Large Eddy Simulation （LES） method, and the indoor thermal comfort of air diffusion at different levels was evaluated. The primary simulations include different ventilation arrangements, and the data from simulations were calculated according to the standard of comfort to analyze and contrast the effects on thermal comfort at different levels.
