Abstract
The current study includes the experimental examinations of the heat transfer behaviours of axisymmetric water jet impinging on a heated plate. Several parameters influencing the thermal performance of axisymmetric water jet are identified and their effects on heat transfer performance are also studied. The key parameters considered is nozzle to target plate gap (20-35 mm). Furthermore, all the examinations here are constrained to a uniform heat flux condition. Results show that the water jet performance can be optimized pertaining to this key parameter. Nevertheless, with the current experimental conditions, the nozzle to target plate gap of 25 mm offers reasonable heat transfer performance and is the optimum one.
