Forced convection over rotating bodies with nonuniform surface temperature
Abstract
An analytical method is developed for obtaining the temperature distribution and the rate of heat transfer in laminar boundarylayer forced convective flow over a rotating body of revolution having a step change in surface temperature. By using a special coordinate transformation and an appropriate series expansion of the temperature, the energy equation becomes expressible in terms of a set of partial differential equations which contain universal functions. These universal functions can be tabulated once and for all. Numerical examples are presented for an isothermal surface and for a surface which has a step discontinuity in temperature for the special cases of a rotating sphere and a rotating disk. These results are compared with values obtained from other formulas available in the literature.
