Numerical study of film cooling on a rotating disk

The development of a heat conducting fluid film on a rotating disk has been analyzed numerically under the planar interface assumption and the film thickness, the flow characteristics, the temperature distribution and the rate of heat transfer are determined. The range of validity of the time scales and Reynolds number bounds have been presented for the existing asymptotic solution for film cooling on a rotating disk. The effects of the Reynolds number Re, cooling parameter β and the Prandtl number σ on the variation of film thickness, and temperature distribution have been examined.
