用ALE方法数值模拟气缸内三维气体流场的研究

NUMERICAL SIMULATION STUDY FOR 3D GAS FLOW IN ENGINE CYLINDER BY ALE METHOD

摘要: 用数值模拟的方法研究气缸内气体流动的全貌以探求合理组织气流的途径,这是当前国内外研究的重要课题,在开发KIVA Ⅱ程序的基础上研究适合该问题的三维ALE方法,并利用此方法数值模拟了一模型问题。

Abstract: It is an important research program based on numerical simulation for studying gas flow in engine cylinder to find a reasonal way of arranging gas flow efficiently. In this paper, a 3D Arbitrary Lagrange Euler (ALE) method is studied for this problem by developing KIVA Ⅱ. Some numerical simulation results are given for an example.
