内燃机缸内复杂空间三维动态网格生成技术
Numerical Method of Generating 3D Moving Mesh for Interior Space of Engine Cylinder with Valves and Ports
-
摘要: 将组合网格拆解为静态和动态2个区域,提出了在活塞和气门运动方向上拉伸和压缩网格空间的算法.实验结果表明:3D动态网格可以应用于内燃机缸内工作过程数值模拟.Abstract: The assembled mesh is decomposed into static and moving zones.An arithmetic of enlarging and compressing grid spaces along the moving directions of piston and valves is presented.Experiments show that the 3D moving mesh is acceptable and applicable in simulating the in-cylinder process of internal combustion engine.
