446 火災外力データベースを用いた自走式プレハブ駐車場火災の数値シミュレーション(S40-2 火災科学とその応用(2),S40 火災科学とその応用)  [in Japanese] 446 Numerical Simulation of Prefab Parking Fire Using Experimental Database of Automotive Combustion  [in Japanese]

A Numerical simulation of car fire in the prefab parking is performed and compared with the results of full scale experiment. The car fire is simulated by LES combustion model based on mixture fraction. Fire spreading between cars is not simulated but the ignition time and the history of heat release rate is assumed for each cars. For the structural safety, surface temperature of beams during fire is important. The predicted time history of beam surface temperature by CFD shows good agreement with measured data.
