LOW-TEMPERATURE VAPORIZATION OF JP-4 AND JP-8 FUEL DROPLETS

This work summarizes an experimental investigation of the low-temperat ure (-15 degrees C to 24 degrees C), ambient pressure vaporization of suspended single and multicomponent liquid droplets in an air stream m oving at relative velocities between 1 and 3 m/s. The work was motivat ed by the consideration of droplet vaporization during fuel jettisonin g from aircraft, and the majority of data was collected using JP-4 and JP-8 fuels. The results showed preferential vaporization of the light er components. A simple semiempirical predictive approach based on sph erical symmetric vaporization and rapid mixing within the droplets was in good agreement with the experimental data.
