Abstract
The effect of turbulence intensity on the transport phenomena over two-dimensional bluff bodies is studied in this work. Simulation is performed for an infinite circular cylinder and a square cylinder with the same hydraulic diameter D, which is also the nondimensional length scale. The computation is performed to cover the cross flow enclosing the laminar and turbulent regime for Reynolds numbers ranging up to 200,000 and inlet turbulence intensities from 5% to 40%. The Reynolds-averaged Navier-Stokes and energy equations are solved along with the transition shear stress transport (SST) model for the closure of turbulence. The results are initially validated with prior works for drag and thermal performance and experimental correlations. The analysis quantifies the influence of inlet turbulence intensity on enhancing heat transfer from the bluff bodies. However, the drag and pressure coefficients are not affected by the variation of inlet turbulence intensity.
