摘要
运用k-ε紊流模型对载人轿车内三维流场进行了数值模拟,其中考虑了人体散热和太阳辐射对速度场和温度场的影响。应用有限容积法和交错网格将计算区域进行离散,用SIMPLE算法计算了空调车内空气流动和传热问题。研究结果为轿车内气流组织的优化设计和舒适性提供了数据支持。
By using k-ε turbulence model, a numerical simulation on 3D airflow field and temperature field inside a car is performed, taking solar radiation and heat dissipation of human body into account. Based on SMIPLE algorithm, the airflow and heat transfer problems are resolved by finite volume method with interlacing mesh. The results provide supports for optimizing in-car airflow and improving comfort of the car.
