Numerical-Experimental Studies of the Heat Transfer in an Air-Cooled Condenser Model

The results of combined numerical-experimental studies of the heat-transfer process in an air-cooled condenser (ACC) model are presented. The range of coordination of rational values of the average heat-transfer coefficient from air-steam mixture to tubes α ¯ a s m the average velocity of air-steam mixture entering the ACC for different temperatures of cooling air, and typical ranges of condensate depression temperatures is scientifically substantiated. A method and an algorithm for determining rational values of α ¯ a s m are outlined.
