Based on the large eddy simulation(LES) of the space fire spread and smoke flow in an enclosure,the fire induced by the burning of missile propellant in a shipboard compartment is investigated.The calculated evolutions of the smoke temperature,the wall temperature and the heat flux on the floor agree with the test data.At the initial fire stage,the air in the compartment is pushed out through the door on the effect of the smoke jostle as a piston motion.The local high wall temperature at the ceiling appears near the line of the ceiling intersecting with the vertical plane where both the fire source and the exhaust exit are in.The wall temperature at the ceiling is higher than that at the floor,shipboard fires possess the violent trend extending up to the upper compartment through the steel shipboard.
