EVAPORATION OF A DROPLET IN FREE MOLECULAR FLOW,

Abstract

The problem of the evaporation of a moving spherical droplet in free molecular flow is studied. An exact solution for the reduction in the droplet size is derived by use of the free molecular limits for drag coefficient and modified Stanton number. An approximate solution is also presented that reduces the complexity of the velocity dependence in the heat transfer relation. Good agreement between the two solutions is demonstrated for a wide range of freestream temperatures. One particular case, using water as the droplet medium, is examined under reentry conditions.
