The Implementation of the Numerical Simulation by Utilization of Pyrosim on the Rectification of the Hazard of Fires

Abstract

In order to verify whether the building can meet the requirements of safe evacuation during a fire or not, finding an optimum design of the smoke exhaust system, the author used Pyrosim software to establish the fire model for the Dongyuan Building, a crowd-intensive public commercial space glutted with restaurants. The fire simulation model was used to simulate to simulate the performance of three types of air vents, each is in 5 different air velocities when two most likely kinds of fire source are on fire respectively. Using the temperature area proportional method of proposed an optimization scheme for the simulation results and verifying its optimization effect. The appropriate air vent position, the air flowrate and a feasible optimization scheme, which can enhance the requirement for the safe evacuation of personnel in the fire event.
