迎面风对航母甲板火灾影响分析
Analysis of the Head-on Wind's Effect to Aircraft Carrier Deck Fire
摘要
Abstract
Fires on the deck of aircraft carrier often pose great hazard to the safety of aircraft carrier and planes.The speed of wind often has remarkable affect the fire on the aircraft carrier deck.The control equations of low Mach flow and the large eddy simulation method of turbulent flows were combined together to analyze the spread and motion of the pool fire smoke on the deck.The variations of the pressure,velocity and heat flux of the fire smoke versus different wind speeds on the deck were simulated.Then experiments were carried out to validate the computed results with a scaled carrier model in the wind tunnel.Results showed that the heat release rate changed Non-monotonously with the wind speed on deck, and the inclining angles of fire and smoke were non-linear to the wind speed on deck.The results might have some value to the fire extinguisher design or shipboard aircrafts safety analysis.关键词
