摘要
为了对内燃机工作过程进行模拟,建立了缸内流体流动的控制方程,采用有限体积法将控制方程离散,通过SIMPLEC算法求解NS方程,并对内燃机工作过程计算域网格的变化进行合并分裂处理,开发了一套用于内燃机工作过程的三维非结构网格CFD程序。将程序用于实际内燃机纯空气循环过程,计算结果分别与实验和其他商业软件结果均吻合较好。
In order to analysis the internal combustion engine, a 3D program based on SIMPLEC algorithm was developed, in which the flow equations were established and discretized by finite volume method. Simulation on air compression in a practical internal combustion engine was performed. The results of numerical simulation were well consistent with experiment data and results from other commercial software.
