【Abstract】 Some algorithms to improve the grid generation in KIVA program are proposed. With them, the grid generation of the ω shape DI chamber with a pit in the cylinder head can be handled with, and the successful aspects of the KIVA method can still be retained. The results show also that by using the algorithms proposed, the spacing of the grid can be adjusted easily.更多还原
