摘要
运用k—ε湍流模型对铁路空调硬座车内气流组织进行了数值模拟。研究了车厢内流场和温度场分布规律 ,并与实验结果进行了对照 ,两者基本一致。研究结果为车内气流组织优化设计提供了依据 ,对改善车厢内人体热舒适环境有指导意义。
The air organization in the air-conditioned compartment was investigated by k—ε turbulence model by SIMPLE programs, and the 3-D distributions of the airflow and temperature field in the chamber were numerically simulated. The agreement between the computed and the measured results of temperature and velocity fields were quite well. It gave a basis for the optimized design of air organization and thermal comfort research in the air-conditioned compartment.
