摘要

本文采用分离涡模拟(DES)湍流模型,对雷诺数为43000的有限高度三维圆柱周围的湍流流场特性进行了数值研究。并将数值计算结果与实验数据进行了比较。结果表明,DES湍流模型能较好地预测有限高度圆柱体在这一雷诺数下的流动。数值结果表明,本文提出的DES湍流模型在研究这种情况下的复杂流动结构方面具有很大的潜力。与大涡模拟(LES)湍流数学模型相比,DES对许多复杂情况下的流动特性预测非常准确,并且可以减少模拟过程中的计算量。

DES of the turbulent flow around a circular cylinder of finite height
The current research work investigates numerically the turbulent flow field characteristics around three dimensional circular cylinder of finite height at Reynolds number of 43000 using Detached Eddy Simulation (DES) turbulence model. Comparison of the numerical results with the experiment data has been taken place. The results reveals that the DES turbulence model is superior for predicting the flow past the circular cylinder of finite height at this Re. The numerical results of this study show the great potential of the presented DES for investigating the complicated flow structure in this case. DES is very accurate for predicting the flow characteristics in many sophisticated cases and can reduce the computational efforts during the simulation process in comparison with Large Eddy Simulation (LES) turbulence mathematical model.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
