摘要:
基于FLUENT软件,通过对等温条件下室内气流场分布和计算所需的资源比较分析,探讨了基于多孔介质模型的直接描述法、平均流速法和有效面积法等渗透式纤维空气分布系统物理模型的3种描述方法的特性。结果表明:直接描述法、有效面积法和平均流速法均能获得相似的室内气流场分布,但前两者需要考虑纤维结构参数的影响。平均流速法所需计算资源少,且不需考虑纤维孔隙率的影响,更适合工程设计人员预测基于渗透式纤维空气分布系统的室内气流场特性,选择较优的系统设计方案。
Abstract:
Using the computer fluid dynamic (CFD) method, three methods to model a fabric air dispersion system (FADS) in penetration mode, namely the direct description (DD) method based on the porous media model, the mean velocity (MV) method and the effective area (EA) method, are discussed in the present work from the aspect of indoor airflow distribution and the computational resource required under isothermal condition. It can be concluded that all three methods can get similar predictions of indoor airflow distribution. Also, the DD method and the EA method need considering the influence of fibre physical structure parameters. The MV method is easy to be implemented and is more suitable for engineering designers to predict the indoor air characteristics based on FADS in penetration mode and to choose the optimum design method of the airconditioning system.
