摘要
介绍了国内某地铁A型车厢内气流组织型式及参数,利用计算流体动力学(CFD)软件Fluent,应用k-ε两方程湍流模型对气流组织进行了数值计算。重点讨论了在相同送风量的条件下,不同送风风速对车厢内温度场和速度场的影响,为地铁车辆空调气流组织的优化设计提供依据。
Air distribution pattern and parameters of A-type metro vehicle in China are introduced. By using the computational fluid dynamics (CFD) software Fluent, airflow is simulated with k - ε two-equation turbulence model. The influence of different supplying wind speed on air temperature and velocity field in the compartment is analyzed under the condition of same supplying airflow rate , the results provide the basis for optimal design in metro vehicle air conditioning system.
