摘要
作者利用计算流体力学中的任意拉格朗日 欧拉 (ALE )计算方法对发动机内经进气门进入气缸套的气体流动过程进行数值模拟 ,得出了气流流经气门时自入口到出口的流动过程速度图谱及稳态时的压力分布 .模拟计算速度图谱与用激光测速仪所进行的测量结果基本吻合 .
In this paper,ALE technique is used to simulate air flow in an engine inlet port.The process of air flow through the engine inlet port and the pressure distribution are obtained.Comparing the results of simulation with the results of measurement with Laser Doppler anemometry tells that both are principle match.
