| Abstract: | Based on the numerical simulation software of PHOENICS version 3.6, air-side heat transfer characteristics of plate fin are simulated and analyzed. Then the heat transfer model for V-type air-cooled condenser is established after modeling methods having been verified correct. At last, air-side fluid flow and heat transfer characteristics with different angles, different tube row number are simulated and analyzed preliminarily. The conclusion is helpful to optimize the designing of the air-cooled.condenser. |
