Abstract: Rigorous experiments stay performed for examining influences of nozzle size on heat dispersal over flat plate concerning constant thermal value 6 W/cm2 . This paper presents the experimental studies on cooling behavior with water jet impingement. Several influencing parameters pertaining to cooling behaviors of striking jets got recognized for investigating impacts over heat transfer characteristics. The parameters taken into account are nozzle diameter (3, 4, 5 and 6 mm), Reynolds number (800, 1600, 2400 and 3200), nozzle to plate spacing (20, 25, 30 and 35 mm) and jet inclination (30⁰, 45⁰, 60⁰, 75⁰ and 90⁰). Additionally, the studies are limited to a constant heat flux situation. The chary interpretations of results tell that performance remains boosted with regard to these key parameters. Nevertheless, for present experimental settings, nozzle diameter of 5 mm provides sufficient thermal features and is the finest one.
