An Insight into the Effect of Sharp and Round Edges on the Flow Field-A CFD Simulation

This paper presents a numerical investigation of pressure drop and distribution in a channel around a sharp edge and a disc that is connected to the base of a circular rod. We have employed computational fluid dynamics (CFD)-Fluent for the validation of our models. It was found that the edge sharpness of the disc influences the pressure drop., i.e sharp edge has higher turbulence and pressure drop. We also observed that pressure drops in the case of the circular disc are less than that of the sharp edge. However, pressure drop has essentially the same values for both shapes after the fluid has passed. Our numerical calculation demonstrates flow pattern follow a similar trend for high and lower Reynolds number (N

), whereas pressure drop is proportional to N
