在欧拉与拉格朗日耦合的框架下，利用有限体积法对非定态三维可压缩流体流动问题给予研究，开发了一般网格下的通用计算程序 该程序适用于计算复杂几何边界条件、运动边界条件等情况下流体流动问题 作为例子，计算了简单中间包内流体的流动情况，给出了随时间变化的流场分布
Under the coupling of Euler and Lagrangian, finite volume method is used to study the flow of non-stationary 3D compressible fluid. The general computational program under general grid is developed. The program is suitable for calculating complex geometric boundary conditions, Fluid boundary conditions and other fluid flow problems as an example, the calculation of a simple tundish fluid flow, given time-varying flow field
