NUMERICAL ANALYSIS OF HEAT TRANSFER USING A BUTTERFLY-SHAPED DIMPLE IN A RECTANGULAR AIR DUCT

In this paper, the heat transfer processes using butterfly-shaped cavities placed in the wall of a rectangular air duct were numerically analyzed. The CFD (Computational Fluid Dynamics)-based ANSYS Fluent program was used. The models were built in 3D under the condition of hot air flow, the Nusselt number, heat transfer coefficient and pressure losses were studied. The geometry of the cavity was placed perpendicular to the flow. The results were compared with a smooth-walled duct and the efficiency was evaluated.

Abstract

In this paper, the heat transfer processes using butterfly-shaped cavities placed in the wall of a rectangular air duct were numerically analyzed. The CFD (Computational Fluid Dynamics)-based ANSYS Fluent program was used. The models were built in 3D under the condition of hot air flow, the Nusselt number, heat transfer coefficient and pressure losses were studied. The geometry of the cavity was placed perpendicular to the flow. The results were compared with a smooth-walled duct and the efficiency was evaluated.
