These results indicate that a vertical surface is more efficienct in the enhancement of heat transfer than a horizontal one, a smaller surface produces higher heat flux, and the grooved surface is more effective in the enhancement and stability of heat transfer. It is also clarified that the optimum size and structure are determined from the sprayed mass flow rate and degree of superheating.
