Investigation of a Mansion Fire Based on Numerical Simulation

Results of a numerical large eddy simulation(LES),which was performed to provide insight on a fire,were described.This fire reconstruction was motivated from the information of a fire which caused a building collapse.According to the actual building geometry,material thermal properties,two possible fire sources in different model scenarios were set.Comparing simulation results of spread trends of obscuration,fire and heat flow with knowledge of fire site investigation,possibility of one fire source can be eliminated while the other is proved.It also indicates that numerical simulation methods can help investigators get more detail and solve the problem that the reconnaissance of the spot can′t be ascertained.Based on numerical investigation,methods to retard fire spread and reduce damage of fire are found.
