摘要：在内燃机工作过程中,气流运动占有十分重要的地位。组织良好的气流运动是改善燃烧过程、提高热效率和降低排放的有效途径。数值模拟方法因具有费用低、周期短、信息量大,能充分反映几何形状的影响程度等特点,被广泛地应用于内燃机气体流动方面的研究。本文概述了内燃机机内气体流动数值模拟的国内外研究现状,指出了目前的数值模拟技术还没有真正达到用于优化设计结构的程度,提出了气体流动数值模拟今后研究的方向。

Abstract: Flow plays a very important
role in internal combustion engine working process.Well-organized flow can
improve combustion,increase thermal efficiency and reduce emission.As a cost
effective and time saving method,numerical simulation can provide the detailed
effect of geometric parameters and is widely employed in ICE flow study.The
current research situation of numerical simulation in ICE flow is
summarized.The current numerical simulation techniques have not really used to
optimize the structure design is indicated.The future research directions of
numerical simulation in ICE flow are presented.
