Considering the characters of the viscoidal turbulent flow over high - speed train , the computing model of the outer fiow field for high - speed train has been established based on the incompressible fluid navier - stokes epuation and the turbulent model of ke two equations . the equation set of the flow field problem via finite element methods ( fem ) has been set up 根據高速列車粘性紊態繞流的特點,在較少簡化的條件下以navier - stokes方程和-兩方程紊流模型為基礎,建立了高速列車外流場的計算模型,在近壁區域采用壁面函數修正紊流模型。
