Abstract
Abstract This paper considers the convective heat-transfer characteristics of the flow in the annular gap between a rotating inner cylinder and a stationary outer cylinder. Heat-transfer measurements are reported for two gap sizes and various combinations of axial and rotational flows. Both smooth and slotted surfaces were used. Measurements for laminar and turbulent-flow conditions followed the trends predicted by theory. An unusual feature of the results for rotational flow without axial flow is the heat-transfer rate in an intermediate flow region existing between the laminar and turbulent regimes. Here, regular ring-shaped vortexes cause a heat-transfer rate even greater than with turbulent flow.
