Numerical Analysis of Fluid Flow and Enhancement of Heat Transfer Over a Square Cylinder with Semicircle Attached at Front and Back Ends

A numerical study of enhanced fluid flow and heat transmission around a square cylinder with semicircles affixed at the front and rear ends was conducted. Both the Reynolds (Re = 100) and Prandtl (Pr = 0.7) numbers are low. By examining both circumstances of a cylindrical square with a semicircle located at the front end and a semicircle linked to the rear end of a square cylinder, a variety of characteristics have been calculated, including the drag coefficient (CD), lift coefficient (CL), and Nusselt number (Nu). The square with a semicircle attached at the front end reduced fluid forces and boosted the heat transfer rate when compared to a square with a semicircle added at the back end.
