The present study involves the experimental investigations of the heat transfer characteristics of axisymmetric water jet impingement on a heated plate. Various parameters affecting the thermal performance of axisymmetric water jet are identified and their effects on heat transfer behavior are also studied. The key parameters considered are jet Reynolds number (800-3200) and nozzle diameter (3-6 mm). In addition, all the investigations here are restricted to a constant heat flux condition. Results indicate that the water jet performance can be optimized with respect to these influencing parameters. However, with the present experimental conditions the nozzle diameter of 5 mm together with the jet Reynolds number of 2400 gives moderate heat transfer behavior and is the optimum one.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
