Heat Transfer in the Wake of a Sectionally Heated Infinite Square Bluff Body

Bluff bodies are objects or structures with a non-streamlined shape that interact with some fluid flow and create complex flow patterns in their wake. Large bluff body structures with heating on multiple sides are common in human society. The heat transfer due to the wake of such structures directly affects the downstream environment and, as such, is of interest to researchers. Flow past bluff bodies and heated bluff bodies has been widely studied - This work expands on pervious research by numerically studying the heat transfer in the wake of a sectionally heated infinite square bluff body. The simulations are run at Reynolds number Re 750 and result in a wake that transitions to turbulent flow past the recirculation region. The bluff body is split into five sections in the spanwise axis and varying patterns of temperature differential is applied to the sections and their sides. The presentation will discuss the heat transfer characteristics, and heat dispersal patterns in the wake.
