Computation of flow and heat transfer in rotating disc systems
Abstract
Finite difference solutions for turbulent, recirculating flow in rotating disk systems at high rotational Reynolds numbers are presented. The mean flow is assumed steady and axisymmetric and a mixing length model of turbulence is used. Results are compared with integral solutions and experimental data. Agreement between finite difference results and measurements is acceptable for many engineering calculations. Integral methods also show promise, although difficulties are identified, and may be used within large heat conduction programs to supply the convective heat transfer boundary conditions.
