Nonequilibrium Flow with Condensation.

Abstract

Diabatic processes dominate compressible flows with phase change where the heat of condensation or vaporization causes changes of enthalpy in the flow. The equations of motion for condensing flows are given in analogy to those of reacting flows and discontinuities are discussed. The nonequilibrium process of condensation by homogeneous nucleation in the supersaturated state is singled out by examples for steady and unsteady nozzle flows, Prandtl-Meyer flow, unsteady expansions and shock waves. A selective guide to the widely dispersed literature is provided, and the early history of the discovery of condensation in supersonic wind tunnels is recounted. (Author)
