Analysis of Condensation in the Centered Expansion Wave in a Shock Tube,
Abstract
A method to determine the onset of vapor condensation by homogeneous nucleation in the unsteady flow in a centered expansion wave generated in a shock tube is described. The test gas, consisting of an inert carrier gas and a vapor, is taken to be an inviscid perfect gas, and the flow is assumed to remain isentropic up to the point of onset of condensation. The latter assumption is valid in experiments where onset is made to occur at the tail of the expansion. Under these conditions the condensation rate is found by combining gasdynamics and the kinetics of nucleation and droplet growth. The method discussed is not limited to a particular choice of the kinetic equations. Finally, we present as an illustration, a procedure with which the nucleation rate in an experiment may be deduced and compared with theory. (Author)
