Heat transfer from axisymmetric sources at the surface of a rotating disk
Abstract
The temperature field and surface heat flux are obtained for a circular band source (heated ring) of arbitrary width on an adiabatic disk surface. The analysis accomodates any radial distribution of temperature or heat flux, and shows the effects of Prandtl number, Reynolds number and radial conduction on surface heat transfer coefficients from various source geometries. Some ideas are presented to extend the results to turbulent flow situations by direct analogy.
