Abstract
The Navier-Stokes equations for laminar source flow between two co-rotating parallel disks were solved by series expansion. The dominant term for the radial velocity profile was then used to solve the energy equation and average Nusselt Numbers were evaluated numerically for several boundary conditions as a function of Reynolds, Prandtl, and Taylor Numbers. For zero rotational speeds the analytical solutions were found to be in excellent agreement with the results of experiments in the laminar flow regime, but an inverse transition phenomenon was observed to limit the laminar regime under certain conditions. In the turbulent flow region an emperical equation for the Nusselt Number at zero rotation was obtained from experimental data and a method for evaluating the average Nusselt Number in the mixed flow regime was developed.
