Porous Jump Model to Interpret the Effect of Perforated Absorber Layer Inclination on Solar Cooker Reliability

Energy is one of the many problems concerning the future of sustainable development since it is limited in quantities. Investments should be re-employed and new technologies should be employed. The use of solar stoves will be one possible approach. In numerical tests of box-shaped solar cookers, the heat absorber plate was copper perforated, and we examined the heat absorption levels for inclined angles of 0°, 3°, 6°, and 9°. The research revealed that the perforated copper lid of the cube-based facade of the solar cooker reached a level of almost 18.4 degrees higher than the regular absorber. Moreover, the cooking time in the box-shaped solar oven will shorten by 21% when the manufacturer uses a perforated copper plate instead of a regular flat one in production. In the first test, the best internal air temperature was obtained by an inclination of 9 degrees. Consequently, the mean temperatures of the perforated copper absorber plate were raised with increasing inclination angles. In this case, the equation for cooking power demonstrated how the cooker steadily heated up and used water in the right range throughout the selected period.
