PERIODIC TRANSONIC FLOW WITHOUT AND WITH CONDENSATION IN A 2-D PLANE CHANNEL

Steady 2-D adiabatic viscous flow and diabatic inviscid flow with energy supply by homogeneous condensation in a channel with a wavy wall have been numerically simulated. The methods used are an analytical-numerical combination procedure for the shock/boundary layer interaction and a diabatic finite volume method to solve the time dependent Euler equations, being linked with the classical nucleation theory and a droplet growth law. The influences of viscous effects and heat addition on the flow field with more than one local supersonic region as well as the choking state have been investigated. The aim is to achieve an adiabatic periodic flow field with imbedded shock waves and a diabatic periodical one including condensation and evaporation phenomena. In the case of adiabatic flow the calculated velocity distribution is compared with experimental and analytical results.
