Abstract: In this paper the numerical analysis study of the effect of almond shaped dimple at four angles on a flat plate is carried out. The heat transfer augmentation is studied by the changes in Nusselt number and friction factor. The numerical analysis is done in ANSYS Fluent. The turbulence model for CFD analysis is chosen after performing validation by the experimental and theoretical results for heat transfer augmentation in flat plate. The experiment is done to study heat transfer enhancement on a plat plate with dimples in a rectangular duct. The heater is provided below the test plate to provide constant heat to the plate. The heat flow characteristics of air after heating in the duct are studied for the enhancement of heat transfer. Because of the vortex generation and flow separation inside the dimples the heat transfer is increased. The analysis is done on dimples at four angles (0°, 90°, 180°, 270°). The maximum heat transfer enhancement is found in 270° dimpled plate. The least heat transfer enhancement is found in 180° dimpled plate. The different heat flow characteristics namely Nusselt number and friction factor are evaluated at different Reynolds number. The numerical results are compared with the experimental results obtained.
