Eine näherungslösung für die kondensation von laminar strömendem dampf mit beliebigen druckgradienten bei kleiner mach-zahl und konstanten stoffwerten

Abstract

Vapor and condensate flows on an arbitrary body curved in flow direction. In the condensate layer we considered only viscous forces and heat flow by conduction. In the vapor layer inertia and friction forces as well as pressure forces were considered. The temperature variation in the vapor layer was neglected. The problem was solved by an integral method. The integral equations are valid for flows with arbitrary pressure gradients with heat transfer. The velocity profile in the vapor layer was assumed to be a function of two shape parameters. Both the quantities of the boundary layer and the heat transfer coefficient were calculated from the stagnation point to the separation point. The average heat transfer coefficient was also calculated, and it includes the properties of the vapor and a heat transfer parameter which were not considered in the work of Shekriladze and Gomelauri.
