Modelling of Box Type Solar Cooker Performance in a Tropical Environment

Abstract

Thermal performance model of box type solar cooker with loaded water is presented. The model was developed using the method of Funk to estimate cooking power in terms of climatic and design parameters for box type solar cooker in a tropical environment. Coefficients for each term used in the model were determined by regression analysis of experimental data. The coefficient of determination of the models established was found to have a range of 0.64 – 0.91 (P < 0.05) which indicates their validity.
