Abstract : The problem of fluid flow and heat transfer characteristics of a cone rotating in a forced flow field is investigated. The flow problem in general involves two parameters, m and s. For heat transfer, one additional parameter, Pr, must be considered. For the special case of a rotating disk in forced flow, the partial differential equations are reduced to a set of ordinary differential equations with two parameters s and Pr. The non-similar boundary layer flow equations are solved for two half cone angles (alpha = 90 degrees and 53.5 degrees) for various Prandtl numbers with s ranging from 0 to about 20. It was found that for s = 10, the first order approximation from the power expansion scheme may not be sufficient. (Author)
