Abstract

This paper presents the experimental and numerical results of forced convection in a rectangular vertical channel. Experiments have been performed for three different fin shapes including, flat plate, cylindrical and diffuse (Narrow wide) (with the angle of θ = 60°) inside the wind channel. The obtained results are presented to show changes in Nusselt numbers and friction factor for all tested winglet types. Furthermore for each type of winglets, test results have been compared between winglets in the term of temperature distribution along the winglets. It has been concluded that, heat transfer coefficient can be improved due to from renewal as periodic of the boundary layer with effect, which of this winglets have particularly placed in the event of groups periodically contracting and expanding in the winglets. Basic conservation equations are solved in continuous flow regime using three-dimensional simulation in the turbulent flow conditions by means of ANSYS Fluent as a CFD program based on finite volume method.
