Numerical simulation of flow and heat transfer around hexagonal cylinder

Abstract

Heat transfer in a channel in presence of a hexagonal cylinder has been numerically investigated. The flow analysis on hexagonal cylinder surrounding laminar and turbulent regime is done with the Reynolds number ranging from 100-50000 and turbulence intensities from 5% to 50%. Air being the flowing medium is considered to have constant Prandtl number. The problem is simplified to a three-dimensional approach. Continuity, momentum, and energy equations are used for the solution of the governing equations. Transition SST Model is used to perform computation of steady variants. The analysis results are verified with correlations and it is being observed that they are similar to each other. This work indicates that SST Model can connect all flow regimes for forecasting the heat transfer with almost no effort.
