Simulation of vessel´s cabin fire based on two-layer zone model

In order to find out the characteristics of fire development, the two-layer zone model was used to simulate the fire in the cabins of vessels. By introducing energy conversation, mass conversation and gas state equation the spreading model for the two adjacent cabins was set up. For illusion, the numerical method was applied to solve the equation sets. Then the simulation program was set up based on the solution. The program results show the variation of the smoke temperature and the sickness of the smoke layer both in the fire cabin and the adjacent one. Compared this model to CFAST, the result was substantially agreed, which means the two-layer zone model could be applied on vessel´s cabin fire simulating.
