摘要
CFD作为暖通空调系统设计优化的有力工具已得到越来越广泛的应用,而CFD模型的建立对于准确模拟空调房间内气流组织乃至人体热舒适来说至关重要。本文研究了近年来暖通空调领域CFD的诸多应用,从网格生成、湍流模型、风口模型、辐射换热和人体模型五个方面分析了CFD建模过程中常见的问题,为如何更好地将CFD模型应用于工程实际提供了参考。
CFD is widely used as a powerful tool for design optimization of HVAC system.The establishment of a CFD model is very important for accurate simulation of the air distribution and human thermal comfort in a ventilation room.Through the review of recent years' CFD applications in HVAC system,the common concerns in CFD modeling are investigated,including grid effect,turbulence model,supply opening model,radiative heat transfer and human model.The reference for better application of CFD model in practical projects is provided.
