Abstract: Based on a full-scale cabin fire test , according to the law of energy conservation, this paper quantitatively analyzes the specific gravity relationship of heat diffusion in the process of fire under different ventilation conditions, such as bulkhead temperature rise, heat transfer to surrounding compartments by radiation and convection, and heat transfer of high-temperature flue gas. The results show that under this test condition, the high-temperature flue gas diffusion and bulkhead temperature rise occupy the main part, while the maximum heat diffusion from the bulkhead to the adjacent compartment is less than 10%.
