Abstract

This chapter represents a validation of the present integral method for the case of a single rotating disk. It was shown that the present integral method is essentially more accurate and enables modelling a wider range of the thermal boundary conditions than the methods of other authors. The novel analytical solution for temperature difference depending on two parameters provides a much better agreement of the Nusselt number with the experiments and significantly expands possibilities for analytical predictions of heat transfer rates over a rotating disk subject to arbitrary thermal boundary conditions. This chapter delivers also a critical overview of the most important experimental results for transitional flow, recommendations for estimation of average heat transfer of an entire disk and briefly outlines some aspects of transient heat transfer over a single rotating disk.
