In this article, a numerical study of the effect of splitter plates located on the wake zone of a square cylinder on vortex formation control and aerodynamic noise reduction is presented. The flow is assumed to be unsteady and is simulated using the URANS equations and applying the turbulence model
as well as the pressure fluctuations by about 50\%. The observation of the structure of the flow indicates that the splitter application is prevented from moving the fluid into the inner surface of the shear layers detached by the downstream splitter. The observation of the structure of the flow indicates that the splitter application is prevented from moving the fluid into the inner surface of the shear layers detached by the downstream spinner. Investigating the details of the unsteady flow structure shows that fluctuations in flow and aerodynamic forces have been reduced due to a longitudinal increase in the wake zone.
