Flow and heat transfer on a disk rotating beneath a forced vortex
Abstract
The integral method of von Karman for calculating the turbulent boundary layer on a rotating disk has been extended to cases for which the outer flow is rotating at a constant angular velocity. The method predicts the nondimensional radial mass flux, the windage and, by analogy, the Nusselt number. It enables quick estimates to be made for the flow over the rear of compressor and turbine disks.
