A CFD Study of Surface Burning Fire Scenario for Evaluating Compliance of the Aircraft Cargo Compartment's Fire Suppression System

To assess whether a halon-replacement candidate can achieve the performance level of halon 1301, a surface-burning fire scenario is conducted as per the Minimum Performance Standard (MPS) for Aircraft Cargo Compartment Halon Replacement Fire Suppression System. In this study, the computational fluid dynamics (CFD) method is employed to simulate a fuel fire occur-ring in a pan placed inside an aircraft cargo compartment. The findings indicate that the height of the pan significantly influences both response time and ceiling temperature, while the distance between the pan and exhaust duct has minimal impact on response time but considerably affects the temperature distribution within the compartment. Specifically, positioning a 60 cm high pan at the center of the cargo compartment results in more stable and elevated ceiling temperatures.
