Study of the Thermal Performance of Different Solar Cooker Geometries With Single and Double Glass

Abstract

The growing use of fossil fuels has led to a significant rise in greenhouse gas emissions, directly contributing to global warming and environmental imbalances. The burning of coal, oil, and natural gas releases large amounts of carbon dioxide (CO2), methane (CH4), and nitrogen oxides (NOX), intensifying the greenhouse effect and accelerating climate change. As a result, transitioning to renewable energy sources is crucial to mitigate global warming, protect public health, and preserve the environment. Solar cookers are an effective technology that captures and converts solar radiation into usable heat for various applications. This article presents a thermal study on three solar cooker designs: rectangular, trapezoidal, and triangular. The goal is to determine the temperatures of the absorber surface and indoor air. The study compares the effects of single and double glazing on thermal performance and considers the impact of adding or removing a thermal load inside the cooker. Additionally, simulations with a primary reflector are also analyzed to assess its effect on performance.
