The Behavior of a Vapor Gas around its Spherical Droplet
Abstract
The behavior of a vapor gas around its spherical droplet is studied on the basis of kinetic theory. The velocity, pressure, and temperature fields are obtained for the case in which the Knudsen number of the system is small but the Reynolds number of the flow is finite. The negative mass flow which was pointed out in two-surface problems but has been considered quite unlikely to occur in these cases is shown to take place for the present problem under easily attainable conditions.
