Simulation of smoke spreading in vessel′s cabin

It supposed that smoke subsiding in each cabin accords with two-layer zone model and smoke spreading model for multi-cabin in vessel was set up by using mass conversation,energy conversation and gas state equation.Finally the fire-shape model was used to simulate smoke′s temperature change in the vessel′s multi-cabins.The result was compared with that computed by CFAST.The time used for computing by the model is 10%～15% ahead that by CFAST.
