Abstract: Experimental study was made to investigate heat transfer characteristics under impinging circular free-surface water jet. The factors included nozzle-to-plate spacing, jet velocity at nozzle exit and phase transition. Heat transfer at the stagnation point and local heat transfer distributions were correlated.
