本文探讨了有限元网格间距对活塞轴对称瞬态温度场计算的影响。研究表明;网格间距对计算有明显的影响。随着网格间距的增大,燃烧期间活塞表面温度沿径向分布畸变现象随之增加。文中还讨论了轴向和径向网格间距比dx/dR对活塞瞬态温度场计算的影响。
This article explores the effect of finite element mesh spacing on the symmetrical transient temperature field of a piston. Research shows that the grid spacing has a significant impact on the calculation. With the increase of the grid spacing, the distribution of piston surface temperature along the radial distribution during combustion increases. The paper also discusses the axial and radial grid spacing ratio dx / dR piston transient temperature field calculation.
