The end wall boundary layer in a vortex chamber

Hydrodynamics and heat and mass transfer of the end wall boundary layer in laminar and turbulent flow regimes were computed using a new approach for the solutions of the end wall boundary layer equations in which a 'radial' boundary layer is represented in the form of a submerged wall jet. This approach has allowed the use of the laws (Volchkov et al., 1960) that govern the development of wall jets. A set of integral momentum and energy equations was formulated and solved, and the laws governing friction, and heat and mass transfer in a spatial boundary layer formed on the end wall of the vortex chamber were derived. Analytical relationships were developed for boundary-layer parameters, including thickness, local friction, heat transfer, and gas flow rate.
