Experiments have been performed to determine average convection heat transfer coefficients for axisymmetric, liquid jet impingement, with annular collection of the spent fluid, Measurements were performed for a small, circular heater affixed diameter (D = 22.2 mm), but for a range of jet diameters (4.42 ≤ d ≤ 9.27 mm), nozzle-to-heater spacings (0.25 ≤ S/d ≤. 6), and confining wall diameters (22.2 ≤ Dc ≤ 38.1 mm). Two different liquids, water (Pr ≈ 7) and a dielectric fluorocarbon (Pr ≈ 25), were employed to study Prandil number effects, and flow rates were varied to provide laminar and turbulent jets over the Reynolds number range 1000 ≳ Red ≳ 40,000. The effect of nozzle-to-heater separation was found to be negligible for laminar jets, while, for turbulent jets, significant heat transfer enhancement could be realized by reducing the separation distance in the range S/d ≳ 1. The effect of the confining wall was discernible only for small values of Dc and was manifested by a reduction in heat transfer wit...
