Abstract

Abstract: A method based on LES and linear programming was proposed for the numerical construction of fire accident. In the simulation with LES method, all the quantities were decomposed into large-scale components and small-scale components. For large-scale components, the direct simulation method was used. For small-scale components, the subgrid model was used. The LES method could improve the simulation accuracy. In the linear programming method, the parameters were locally linearized to solve the optimization problem. It could improve the simulation efficiency. The method was applied to the numerical reconstruction of a wholesale market fire in Shanghai. The spread of fire and smoke was analyzed. The simulation results agree well with the fire reconnaissance data, which validates the proposed method.
