摘要
作者将一个非线性涡粘度湍流模型进行修正后应用于内燃机缸内湍流流动计算,此模型采用了应力张量和应变张量的三阶相关关系,对几种不同类型内燃机气缸内的流动进行计算,结果表明此模型在定性和定量上都较之k—ε模型有较大的改进,其适用于内燃机缸内湍流流动的数值模拟。
After being corrected, a nonlinear eddy-visconsity model has been application to in-cylin-der flow calculation in ICE. This model adopts a cubic relation between the stress and strain tensors. Numerical simulation results for in-cylinder flows at several engines show that the new model is a better improvement over the K-model. The model fits numerical simulation of in-cylinder turbulent flow in ICE.
