Abstract
Heat transfer experiments for an asymmetric confined jet have been made for several nozzle locations of different eccentricities. The Craya-Curtet number, usually regarded as a similitude parameter for the flow pattern of an axisymmetric confined jet, has been found to be a useful parameter for correlating the measured heat transfer data. Therefore, it can be regarded to be a similitude parameter for heat transfer in the studied type of separating and reattaching flow. Measured values of the maximum Nusselt number and their positions at different peripheral angles θ have been plotted against the space L between the tube wall and the nozzle corresponding to each peripheral angle. Form this examination, a possibly existing secondary flow in a cross section has been suggested to affect the heat transfer characteristics of an asymmetric confined jet only slightly. Lastly, it has been found that slightly better overall heat transfer can be obtained with a larger eccentricity of nozzle location.
