Evolutions of gas temperature inside fire compartment and external facade flame height with a casement window

摘要: Abstract Gas temperature of a fire compartment and external facade flame height pose serious hazard upon urban environment safety, where the window (ventilation) condition has an essential impact. This paper investigates their evolutions with casement various opening angles, which not been quantified previously although is commonly used practically. Experiments are conducted employing model-scale under different heat release rates dimensions angles. It found that upper-part gas inside increases, while critical rate for ejection as well decreases, increasing angle it less than 60 degrees (θ
