Abstract
This numerical study attempts to discuss about the effects in vortex shedding and aerodynamic parameters due to heating the top surface of a square cylinder for various Ri values (0 < Ri < 1) at Pr = 0.71 and Re = 100. Numerical calculations are carried out using a finite volume method based on the PISO (Pressure-Implicit with Splitting of Operators) algorithm. We have used ANSYS Fluent for the numerical simulation. The results in this study are promising and we found that the surface heating would rather changes or modifies the flow field and the vortex shedding phenomenon behind the square cylinder. Also it is observed that heating plays a critical role in the integral quantities such as aerodynamic coefficients, Strouhal number etc.
