Abstract
The current research encompasses the experimental studies of the heat transfer performance of axisymmetric water jet impinging on a heated plate. Several parameters affecting the thermal behaviour of axisymmetric water jet are identified and their effects on heat transfer characteristics are also studied. The key parameters considered is nozzle tilt angle (30-90°). Besides, all the studies here are limited to a constant heat flux condition. Results show that the water jet performance can be optimized pertaining to these key parameters. Nonetheless, with the present experimental conditions, the jet tilt angle of 60º provides reasonable heat transfer
characteristics and is the optimum one.
