This paper mainly focuses on the design of solar concentric parabolic cooker with proper arrangement of phase change material (PCM) heat storage system. The receiver is a hollow concentric cylinder with inner and outer radii being 0.09 m and 0.1 m, respectively. The thickness or the gap between the two layers of the receiver is 0.01 m and is filled with heat transfer oil. The outer layer of the receiver is surrounded by the vertical cylindrical PCM tubes of diameter 0.025 m. The three modes of heat transfer, radiation, convection, and conduction, are explained and analyzed by heat transfer network. The schematic view of the receiver is shown with the help of sketchup software. The performance parameters, heat loss factor, optical efficiency factor, cooking power of the solar cooker, were calculated with and without PCM in the receiver. 7.74 W m−2 and 2.46 W m−2 are the heat loss factors, and 0.098 and 0.22 are the optical efficiency factors of the solar cooker without and with PCM presented in the receiver. The optical efficiency factor of the solar cooker with PCM receiver is two times more than that receiver without PCM. The cooking power of the solar cooker with PCM receiver is 125.3 W which is 65.6 W more than that of the cooking power without PCM receiver. From these results, it can be concluded that the design of PCM solar cooking system can expand the applicability of solar cookers as a compatible cooking solution for cooking applications instead of using fossil fuel based cooking systems.
