The goal of this senior design project was to achieve a safe external surface temperature below 60 C for a prototype combustion system designed to burn menstrual products at 1000 C, particularly targeting the waste disposal issue in India and Nigeria. Sponsored by the Gates Foundation for Biomass Controls PBC, the project utilized simulation-based approaches with ANSYS Workbench software, focusing on thermal and airflow models to improve user safety by lowering the external temperature of the device. By adjusting insulation, airflow, and heat exhaust within the simulations, the project aimed to identify design solutions to maintain a surface temperature safe to touch, enhancing the device's safety and efficiency in disposing of menstrual hygiene products in an environmentally friendly manner.
