“…To that end, this paper's primary deliverable is a set of experimental results from the first run of a solar cooker with a box shape and a porous absorber plate. The porous absorber increases the speed at which heat is transferred to the cooker's air [29]. Many researchers have tried to improve the efficiency of solar air heaters and other sun thermal conversion equipment by employing this technical method.…”

Sustainable development is confronted with various challenges, and one of them is the scarcity of energy. To meet the needs of present and future generations, investments, technologies, and institutions need to evolve. One promising solution is the utilization of solar cookers. These cookers operate without the need for fuel or coal, resulting in cost and time savings. In the present study, two box-shaped solar cooker models were tested under identical conditions to assess their thermal performance and identify areas for improvement. The first model employed a copper absorber plate, while the second model utilized copper foam sheets with a porosity of 10 pores per inch (PPI). The experimental testing took place in Baghdad City, Iraq, in September 2022. The cookers were positioned towards the south at a latitude of 33.3° N and a longitude of 44.4° E. During the experimental testing, the copper foam with 10-PPI was used as the heat absorber plate, and various inclination angles (0°, 3°, 6°, and 9°) were examined. The resu lts demonstrated that the solar cooker with a 10 PPI copper foam absorber achieved a stagnation temperature approximately 25.8 degrees higher than a standard absorber of the box-shaped solar cooker. Furthermore, using a 10-PPI copper-foam absorber plate reduced the cooking period in the box-shaped solar oven by up to 33% compared to a flat conventional absorber plate. The mean temperatures of the 10-PPI copper-foam absorber plate increased as the inclination angle rose, reaching its optimal internal air temperature at an inclination of 6 degrees. The equation of the cooking power provided a reliable indication that the cooker consistently cooked food and boiled water within an acceptable range.

Two box-type solar cooker (BTSC) prototypes were tested to examine thermal performance under identical conditions. The first box solar cooker used an absorber plate fabricated from copper, and the second box solar cooker used 40 pores per inch (PPI) of copper foam sheets. Many experiments on solar cookers were carried out in September 2022 in Baghdad, Iraq, where the solar cookers were directed to the south and situated at latitude 33.3°N and longitude 44.4°E. In the experimental testing, copper metal foam 40 PPI is used as a heat absorber plate at various absorber plate heights (1, 3, 5, and 7 cm). The results showed that the solar cooker with a 40 PPI copper foam absorber experienced a stagnation temperature of roughly 17° higher compared to a BTSC with a standard absorber. A copper foam 40 PPI absorber plate can reduce cooking time in a BTSC by as much as 23% compared to a standard flat absorber plate. The percentage of increase in the solar cooker’s internal temperature with an increase in absorber plate height from 1 to 7 cm for 40 PPI copper foam absorber plate is approximately 16.1%. The acceptable range for the equation of cooking power indicates that the cooker can be relied upon for consistently cooking food and boiling water.
