Flame Propagation over Liquid Fuel at Sub-flash Temperature

抄録

When the flame propagates over liquid fuel at sub-flash temperature, heating the surface of the flame are required, and the surface-tension-driven flow, which is caused by the temperature distribution at the surface and flow, which is caused by the temperature distribution at the surface and controls the heat transfer at the tip of spreading flame, plays an important role. The characteristics of the surface-tension-driven flow are classified in to three groups (laminar, transient and turbulent). The relations between the flame spreading rate and the initial temperature are also classified into three groups according to the characteristics of the flow in the neighbourhood of the tip of a spreading flame. The flame spreading rates at sub-flash temperatures are calculated by using only one experimental value of flame spreading rate at the flash temperature. The numerical results coincide with the experimental results.
