Abstract
In this study, we investigate the flame spread characteristics of binary mixed liquid fuels that are
both in super-flash condition. We propose a method for estimating flashpoint and flame spread
rate for binary mixed liquid fuels from binary vapor concentration distribution and compare
these estimated values with experimental results. In addition, we measure the flame height and
center of the flame leading edge for binary mixed liquid fuels. The results show that, when the
flashpoint of each single fuel is known, the flashpoint of the binary mixed liquid fuel can be calculated.
Moreover, the fuel that most influence combustion changes near the intersection of vapor
concentration distribution in accordance with Raoult’s law. Photographs of the flame indicate
discontinuity. We can calculate flame spread rate by using the ratio of each diffusion coefficient to
judge equivalently. Finally, it is found that the flame height and center of flame leading edge are
proportional to total vapor concentration of the binary mixed liquid fuels.
