针对现有的CFD模拟计算双层皮自然通风的方法中存在的问题,设计提出适用于热压与风压共同作用的双层皮自然通风计算的CFD模拟方法,并设计实验验证该模拟方法的准确性。该方法中引入多孔介质模型以节省网格数目和计算时间,同时保证计算精度,可被广泛应用于双层皮幕墙通风的模拟计算和优化设计。
In order to solve the existing problems in CFD simulation of two-skinned natural ventilation method, a CFD simulation method for natural ventilation of two-skin skin is proposed, which is suitable for co-operation of hot pressing and wind pressure. accuracy. The method introduces porous media model to save the number of grids and calculate the time, and ensure the accuracy of calculation. It can be widely used in the simulation and optimization of double skin curtain wall ventilation.
