HEAT RELEASE RATE OF SUBWAYCAL IN FIRE USING REDUCED-SCALE MODEL

초록

Heat release rate (HRR) of a subway car in fire is measured for various positions of ignition source and simulated materials with different combustibility by using a reduced-scale model. The maximum values of HRR are not almost dependent on the positions of ignition sources in the same material but the times reached its values are very different for the ignition positions. Opening area of the subway car is one of main factors for the maximum HRR but combustibility of materials has influence on the max HRR. Finally the HRR curve is compared to that of the real-scale passenger railcar fire test
