Abstract
In mixed-flow turbo-machines the energy transfer results partly from fluid deflection and partly from Coriolis forces due to the radial motion. The relative motion produces another effect not occurring in axial machines, namely that of slip or relative eddy. In this paper a conformai transformation theory is developed for radial bladed conical flow machines along similar lines to that of Busemann.
The flow is regarded as the superposition of source/vortex prewhirl flow and a blade lifting vortex. The lift components due to Coriolis forces and deflection are thus separable. The theory also permits the calculation of surface velocities and streamlines. The main intention is to provide an exact theory for comparison with the extended Schlichting analysis of Pollard.
