摘要
对汽车发动机进、排气道流动模拟的数学模型与数值算法进行了理论分析与初步研究，并针对可压缩流动的特点，在ＳＩＭＰＬＥ算法的基础上推导了新的考虑密度变化的压力修正方程。
The mathematical model and numerical algorithm to simulate the gas flow in intake and exhaust ports of automotive engines are theoretically analysed and basically studied. Adapted for the properties of compressible flows and based on the SIMPLE algorithm, a new pressure correction equation which now takes into account the density variation is derived.
