In this study, a plate fin heat sink is utilized for a TEG system to recover the waste heat which generated from a bronze ingot casting furnace with an impingement flow direction. Three-dimensional (3D) numerical model for the heat recovery system including the TEG module and the heat sink are developed and solved by using the commercial software ANSYS Icepak 19.2. Both of the effects of convection and radiation are considered. The ideal maximum power output of TEG module is evaluated by one dimensional model based on the temperature distribution of the TEG module which obtained from the 3D numerical simulation. The net power output of the TEG module is obtained by subtracting the pumping power from the ideal power output of the TEG module. The effect of operating parameters (velocity and temperature of waste heat flow) and fin parameters (fin height and numbers) on the heat transfer, TEG power output and efficiency are determined. The obtained conclusions in this research could provide valuable information for the design of an industrial TEG and waste heat recovery system.
