Internal heat transfer of a solar box cooker's double glass cover has been studied using MoS2-Fe2O3-Cr2O3 nanomaterials. By using the performance of nanomaterials with and without covering materials, the design was able to achieve the bar plate temperature of roughly 163.74 °C and 113.34 °C below solar radiation of 1037 W/m2.Fuzzy intelligent logic and Cramer's rules are used to run the simulation model. It was 91% in line with the trial's findings.
