“…Impinging jets have been used to transfer heat in diverse applications, which include the drying of paper and the cooling of turbine blades. Hollworth and Durbin [1] investigated the impingement cooling of electronics, Roy et al [2] investigated the jet impingement heat transfer on the inside of a vehicle windscreen and Babic et al [3] used jet impingement for the cooling of a grinding process. In these, and in other cases, research has been conducted with a specific application in mind but there have also been many fundamental investigations into the fluid flow and heat transfer characteristics.…”

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.

a b s t r a c tThe present study examines the effect of flow and geometric parameters on the performance of solar thermal collector provided with impinging air jets. The investigation has been carried out in terms of performance defining criterions which are pertinent to determine the optimal design of impinging jet solar thermal collector. The experimental investigation indicated that the impinging air jets enhances the thermal performance but at the same time the friction power penalty also increases which depress the overall performance of the system. In view of this the preference selection index (PSI) approach based methodology has been applied using various performance criterions in order to determine the optimal design of the parameters which deliver maximum thermal performance with minimal increase in friction factor inside the collector duct. The optimum configuration of the parameters obtained as a result of proposed method is: streamwise pitch ratio of 0.435; spanwise pitch ratio of 0.869; jet diameter ratio of 0.065 and flow Reynolds number of 16,000.
