摘要
本文采用有限体积法求解具有原始变量的低速N一S方程,对列车周围流场进行数值模拟研究.计算中对转向架和受电弓处作了简化处理,得到了三车编组情况下列车表面压力分布及气动阻力系数,并与列车模型风洞实验结果进行了对比.
In this paper,N-S equations with primitive variables are solved by finite vol-ume method to study flow field around train. Air pressure distribution on sur-face of train(3 cars)and aerodynamic drag coefficient are obtained with sim-plified bogies and pantographs in calculations. Computational results are alsocompared with those given by model test in wind-tunnel.
