Optimization of Ventilation Pattern at Subway Platform Fire Based on CFD

摘要：

3D numerical simulation is carried out for subway platform fire by applying normal turbulence double equations model. The standards of personnel safety evacuation are drawn and the optimum control model of ventilation pattern is set up. The mathematical model is verified through comparing simulating results of velocity parameters to measure results on non-fire state. Simulating result of ventilation pattern is analyzed and adjusted by example until it meets the estimation standard of personnel safety evacuation. The research result can offer the reference for estimation and optimization of the ventilation pattern at subway platform fire.
