Design, development and optimization of a solar cooker: Householdscale application in Lubumbashi (DR Congo) (Research)

This thesis focuses on the design, development and optimisation of a solar cooker for domestic use, with the aim of creating a solar cooker capable of competing with the charcoal-based combustion system widely used in Lubumbashi (DR Congo). Lubumbashi faces recurring problems of access to energy, particularly for cooking. The research carried out as part of this thesis will be based on a multidisciplinary approach, combining aspects of engineering, physics and energy optimisation. Firstly, an in-depth literature review will be carried out to gather existing knowledge on solar cookers, solar absorption materials and heat transfer techniques. Next, a design methodology will be developed, taking into account the specific climatic conditions of the city of Lubumbashi, such as sunshine, ambient temperature and seasonal variations. Several prototype solar cookers will be built and tested, using recyclable, affordable and locally available materials. The thermal performance of the prototypes will be assessed by measuring the temperatures reached and the cooking times required for different recipes and quantities of food. This research will help to improve the energy efficiency of the solar cooker. Energy optimisation techniques such as the use of thermal insulation materials, optimising the geometry of the cooker and adjusting design parameters will be explored. Computer simulations will be carried out to assess the impact of these improvements on the performance of the solar cooker. Finally, full-scale tests will also be carried out in households in the city of Lubumbashi to assess the feasibility and acceptance of the solar cooker by the local population. Surveys and interviews will be conducted to gather feedback from potential users, in order to identify the benefits, limitations and possible improvements of the solar cooker.
