利用格子波尔兹曼方法计算了高速列车的空气动力学问题.计算采用真实非简化列车几何,千万量级空间网格.不同工况的结果均真实反应实际情况,表明格子波尔兹曼方法在实际工程计算中有非常广阔的应用空间.
The aerodynamics of high-speed trains is calculated by the Lattice Boltzmann method, and the calculation is based on the geometric and tens of millions-dimensional grid of real non-simplified trains.The results of different working conditions all reflect the actual situation, indicating that the lattice Boltzmann The method has a very wide application space in the actual engineering calculation.
