Heat Transfer between a Pool Fire and Water Mist Droplets in a Compartment

Technical constraints and standard regulations rendered the engines more efficient but also more prone to fire.Sound insulation and higher operating temperature have increased the odds of fires.The threat is especially prevalent in public transport buses and coaches because the maintenance time is kept as low as possible.Water mist could be a device to extinguish starting fires, even in a cluttered compartment.In this preliminary paper, the interaction between water mist droplets and a n-heptane pool fire is studied through the influence of the nozzle operating pressure on the flow characteristics, water mist cooling performance and heat flux reduction.
