Mathematical modeling and validation of solar-induced ventilation system for vehicle cabin cooling in hot parking conditions

Exposure to direct sunlight raises interior temperatures in vehicle cabins, risking heat-related illnesses. Solar passive techniques mitigate this issue, especially during hot parking conditions. However, a comprehensive mathematical model encompassing both solar chimney and...
