Solar cooker fuzzy rules implementation to analyze thermal applications

Abstract

A design, construction, & performance evaluation of the cooker with a copper absorber panel painted mat black and filled with 1 g of NiO2 nanoparticles has been constructed. The temperature components have been solved using a Laplacian technique, and the results are compare with trial observations by calculating the RMSE and R2 values. The values of RMSE and R2 for the temperature of the glass cover were determined to be 0.115 and 0.993, 0.118 and 0.997, 0.110 and 0.996 for the lid of the cooking vessel, 0.119 and 0.996 for the base of the cooking vessel, and 0.114 and 0.998 for the cooking fluid, respectively.
