| Abstract: | The phenomena and mechanism of flame spread over oil floating on water were studied using temperature measurements made by
fine thermocouples and an infrared camera, schlieren images of surface convection and video recordings of flame spread. The
experimental results reveal that the floating-oil depth greatly affects the average rate of flame spread and average flame
pulsation wavelength. The surface tension effect is the main cause of surface convection, which controls flame spread. Momentum
loss and heat loss from forward-flowing hot oil to water play an important role in retarding flame spread for oil thicknesses
less than about 8 mm. |
