Abstract
The effects of surface radiation and the combined effects of surface radiation and pressure on flame spread over thermally-thin fuels in a quiescent microgravity environment were investigated numerically. Results show that the effects of surface radiation and the combined effects of surface radiation and pressure on flame spread were significant. The flame spreading velocity decreased with increasing the surface radiation. The flame spreading velocity increased with increasing the ambient pressure as the effects of the surface radiation were considered in the equations. A non-dimensional parameter was proposed to analyze the effects of the surface radiation on the flame spreading characteristics to further clarify the flame spreading mechanisms under microgravity environment.
