Abstract
The influence of initial temperature of droplet on the evaporation characteristics of the RP-3 aviation kerosene was experimentally studied.The variation of squared non-dimensional diameter,transient evaporation constant,droplet life, and thermal expansion ratio was explored in detail under different conditions. It is observed that evaporation efficiency is mainly improved by cutting down the heating time at the beginning for droplets of higher temperature.When the initial temperature of droplets is increased from 293.8 K to 373.1 K, the droplet evaporation time will be reduced by 31.55%, 32.25%, and 34.73%, for three different ambient pressures, respectively.In addition,it is also found that for droplets of higher initial temperature,the supercritical light-spot appears earlier on the droplets with a larger diameter.
