Comparsion of Turbulence Models on Calculation of Inner Flow Field of the Cross Flow Fan
摘要
Abstract
A two-dimensional model of the cross flow fan is established in this paper,using four different turbulence models (RNG k-ε,RSM,DES,LES)for unsteady calculation,through comparsion of transient velocity distribution and transient vorticity distribution in inner flow field and time-average velocity distribution,time-average pressure distribution along an outer circumference to determine the differences of inner flow field with different turbulence models,it provides reference for numerical simulation of inner flow field of the cross flow fan.关键词
