Abstract

A numerical investigation on the flow behavior past a circular cylinder at Reynolds number of Re = 1.0e6 - 8.4e6 is performed using Computational Fluid Dynamics (CFD) approach. The study is carried out using an overset grid method employing the two-equation eddy viscosity Menter SST turbulence model. For preliminary studies, simulations of two-dimensional as well as infinite length circular cylinders are conducted and compared with available measurement data. The predicted drag coefficient and Strouhal number are in the good agreement compared with the measurements. With the presence of a flat plate, CFD simulations demonstrate that the three-dimensional effects strongly influence the flow behavior near the junction. The horseshoe vortex and the characterized 3D flow phenomena are observed and investigated in the present study.
