Abstract: Trenuous experiments are conducted to investigate the effects of jet Reynolds number on heat dispersal over flat plate concerning constant heat flux of 6.25 W.cm-2 . Aimed at that four different jet Reynolds numbers of 800, 1600, 2400 and 3200 are picked, above and beyond, jet flow rate and nozzle diameter of 30 lph and 5 mm, respectively. As anticipated, it is witnessed that the temperature upsurges in radial course. Additionally, the witnessed temperature distribution is axisymmetric. Furthermore, it discloses that the temperature decreases with jet Reynolds number. In addition, the witnessed temperature variation is more or less linear. Similarly, it also unveils that the Nusselt number declines along radial route. The witnessed Nusselt number distribution is axisymmetric on top. Additionally, it also divulges that the Nusselt number upsurges with jet Reynolds number. The witnessed Nusselt number variation is more or less linear as well. However, the jet Reynolds number of 2400 bids medium and ideal cooling performances.
