Investigation on the Effect of an Inclined Splitter Plate on the Hydro-Thermal Behavior Around Circular Cylinder in a Channel

In this work, the effects of a splitter plate on the hydro-thermal characteristics around a circular cylinder in a channel was studied. The two-dimensional unsteady and incompressible flow and heat transfer was investigated numerically by solving the continuity, x - and y - momentum and energy equations using finite volume methodology by FLUENT. The second order upwind scheme is used to discretize convective and diffusive terms. The resulting algebraic equations are solved by PISO algorithm. The splitter plate length varies from 0.25D to 3D and it's angular position varies from 0° to 45° with Reynolds numbers 600, 800, 1000, 1200 and 1500. With increasing the splitter plate length Drag coefficient decreased continuously and the surface Nusselt number of cylinder is decreased with adding a splitter pale with length more than 1.5D. in this manner by increasing Reynolds number, effect of adding splitter plate decreases.
