Numerical Simulation Of Flows Past A Circular And A Square Cylinder At High Reynolds Number, And A Curved Plate In Transitional Flow, Ling Zhang
McKelvey School of Engineering Theses & Dissertations
Increasing the prediction accuracy and computational efficiency of turbulence models at high Reynolds number remains a challenging problem in Computational Fluid Dynamics (CFD). In this paper, several turbulence models are applied for numerical simulation of flow past a circular and a square cylinder at high Reynolds number. Wray-Agarwal (WA) turbulence model is a recently developed one-equation turbulence model derived from k-w closure. Comparisons are made among computational results from WA model, Spalart-Allmaras (SA) model, the shear stress transport SST k-w model and the standard Wilcox k-w model. For circular cylinder, the computations are performed for Reynolds numbers and and simulation …
