Abstract: The application of a porous media on square cylinders to reduce drag in cross-flow is an active research area. Be that as it may, the related stream incited sound in the encompassing flow likewise experiences decrease, an angle which has gotten less consideration. This paper exhibits a numerical strategy for coupled streamlined and aero acoustic estimations for low Mach number flow current pass a square cylinder with permeable cover. Computations are performed at a subcritical Re of 54,800 using URANS technique and FW-H acoustic analogy. The cylinder without porous cover is subjected to an incoming flow is considered for validation against measurements. A significant drag reduction and sound reduction is observed with the presence of the porous layer. Comparisons are made among the modified cylinder and its unmodified counterpart.
