储能式现代有轨电车空调系统气流组织研究

Study on airflow organization of energy storage modern tram HVAC system

分析现代有轨电车空调系统气流组织的组成情况,先通过建立数学模型,确定采用Reynolds平均法对车厢空气的湍流运动进行模拟,再对车厢进行简化物理模型模拟,划分计算网格,根据边界条件进行整车气流组织仿真计算,对计算的结果进行了评价,最后给出了一部分优化的建议。

This paper analyzes the formation of HVAC system airflow organization in modern tram,builds mathematic model,adopts Reynolds average method to simulate the turbulent flow of the air in the vehicle, simplifies the physics model,and divides calculation griddings. On the basis of boundary conditions,it simulates the air flow organization of the whole vehicle, evaluates the simulation result and discusses several optimized ways.
