摘要
Abstract
Modelling and solution techniques for numerical simulation of engine cooling fans are presented in this paper. In the article, the engine cooling fan of heavy vehicles is studied as the object. The authors use the method of dividing grid according to the regions and employ sliding mesh technique to conduct numerical simulation and aerodynamic performance and noises study on 3-D flow field of cooling fan of heavy vehicles. For the simulation of steady flow field, RNG k-e turbulent model base on RANS (Reynolds averaged N-S equations) method is used, and for the simulation of instantaneous flow field, the method of LES (large eddy simulation) is used. The pressure analysis and the velocity analysis of fans' flow field are presented. The influence factors on flux of the fan and aerodynamic noise of the fan are discussed as well.关键词
