HEAT TRANSFER FROM A FLAT SURFACE BY ROTATING FLOWS,
NAVAL WEAPONS LAB DAHLGREN VA
The heat transfer by rotating laminar flows from a flat surface was investigated. Dissipation is considered, whereas free convection effects are neglected. The calculation is based on the knowledge of the flow fields, which have been studied in previous papers by the authors. In these papers, axisymmetric boundary layers were re-examined according to an extended boundary layer theory. The basic ideas of this theory are applied to thermal boundary layers. The energy equation is reduced to an ordinary differential equation. In the special case of negligible dissipation the heat transfer of Karman-type flows can be compared with existing experimental data. The agreement is good. Author
