基于KIVA的内燃机缸内湍流三维数值模拟

Three-dimensional Numerical Simulation of Cylinder Turbulent Flows of Internal Combustion Engines Based on KIVA

内燃机缸内气体流动是极其复杂的三维湍流运动,本文利用CFD软件KIVA对内燃机缸内湍流进行了三维数值模拟,总结出内燃机缸内流体的流动特性,对内燃机的缸内流体研究具有重要的指导、借鉴意义.

Gas flows in the cylinder of internal combustion engines are invariably complicated three-dimensional and turbulent.This thesis performs a comparative study on three versions of eddy-viscosity models（EVM）,i.e.and gives the characters of turbulent flows of internal combustion engines.The work has very image value to the study of engines.
