Experimental Investigation of Heat Transfer Coefficient in Parabolic Dish Solar Cooker with Thermal Energy Storage System

Abstract: The use of solar cooking can help cut back on the consumption of fossil fuels. Due to the rising expense of fossil fuels, there is a great demand for an energy efficient and affordable solar cooking technology, and it is currently the most popular study topic worldwide. This study examines how a thermal energy storage material (Erythritol) can improve the thermal performance of solar parabolic dish cookers. On the cooking vessel with and without thermal energy storage material, tests for stagnation temperature and water boiling and cooling are performed. In terms of thermal performance, heat loss factor, optical efficiency experimental results for the two instances are analysed. Heat loss factor was found to be 16.8 W/m2K and 28.21 W/m2K in with and without thermal energy storage system
