根据可压缩粘性流体的N-S方程和k-ε双方程湍流模型,运用移动网格技术,采用有限容积法对磁浮列车以500 km/h速度运行时的会车压力波进行了数值计算研究,计算结果与现车试验结果相差10%以内,表明了本文计算模型和方法的正确性;文中还研究了交会过程中列车周围的流场分布,结果表明:当列车交会时,两车之间的流场相互叠加,而两车之外的流场分布在整个交会过程中变化不大。 According to the Navier-Stokes equations and the k-ε turbulence model of two-equation turbulent flow of compressible viscous fluid, the moving-grid technique is used to calculate the pressure wave of a car driven by a maglev train at a speed of 500 km / h using the finite volume method. The result is within 10% of the current vehicle test result, which shows the correctness of the model and method. The flow field around the train during the rendezvous is also studied. The results show that when the rendezvous is between two vehicles The fields are superposed on each other, while the distribution of the flow field outside the two cars changes little during the entire rendezvous.
