The phenomenon of fluid flow past a bluff body can be ubiquitously perceived both in nature as well as a multitude of engineering applications. The pragmatic and real-world significance of this problem combined with its simple yet intricate physics has turned the heads of quite a few researchers in the past century. The present study deals with the numerical investigation of flow characteristics around a modified circular cylinder with a slit. The numerical simulations were performed with a finite volume-based solver at a Reynolds number (Re) = 2500 based on the cylinder diameter (D) and the centerline velocity at the inlet, which can be considered as the lower critical value for the dynamic shift from laminar to turbulent flow regime. The upstream and downstream stagnation points on the cylinder surface were connected by a slit. The slits implemented were parallel, converging, and diverging with respect to the direction of flow and amalgamated with one cylinder having no slit, a total of four cases were solved. The windward width of parallel and converging slits was 0.1D and the diverging slit being a mirror of the converging slit. The end-width ratio (Φ) of the converging and diverging slits was 1.5. The results indicated that incorporation of slits in the modified bluff body contributes to drag reduction by the creation of self-issuing jets which affect the wake vortex shedding process downstream of the cylinder. The parallel slit being the most efficacious one leads to the highest reduction of drag due to the formation of smaller sized vortices as compared to convergent or diverging slits in the wake region of the cylinder.
