Abstract

An experimental analysis of a stepped solar box cooker (SSBC) improved using energetic SiO2/TiO2 nanoparticles. They were used in different ratios between 5% to 25% as a coating on a bar plate to enhance thermal performance. The SSBC was assessed experimentally to obtain a cost-effective solution and the best performance for the bar plate temperature, enabling increased cooking activities performance. The furious SiO2/TiO2 nanoparticles were coated over a bar plate, which allows them to absorb more solar radiation and increase the system of inner moist air temperature. The SiO2/TiO2 nanolayers used as 15% improved overall thermal efficiency by 31.42% of the system. The bar plate performances coated with SiO2/TiO2 nanolayers and used in SSBC were compared to other doping nanoparticles percentage for their solar thermal characteristics. The SiO2/TiO2 nanolayers coated by the SSBC is enabled to increase the performance by about 31.77%, 37.69%, 49.21%, 36.99%, and 34.66% when was used 5%, 10%, 15%, 20%, and 25%, respectively and compared to that of single nanolayers (SiO2, TiO2) of convention cooker.
