分离涡模拟类方法发展及在叶轮机械内流场的应用
Review of Development of DES and Its Application in Turbomachinery
摘要
Abstract
Detached eddy simulation(DES) is one of the numerical simulation methods with high-precision and feasibility in engineering,which can support refinement design for turbomachinery.This paper briefly reviews the development,problems and solutions of DES method,and illustrates the construc tion idea of the DES method based on one-equation turbulence model.In the aspect of accuracy verification,based on the simulation results of the classical physics model,the prediction accuracy of DES method for separation and transition phenomena which is ubiquitous in turbomachinery is analyzed.On the basis of this,the prediction accuracy and application of the DES method in internal flow field,like cascade,subsonic and transonic turbomachinery,are briefly reviewed.Finally,the issues that need seri ous consideration for application of DES method to turbomachinery are presented.This paper provides reference for application of DES method to high-performance compressor design.关键词
