Abstract:

A methodology is developed for calculating the heat transfer coefficient on the surface of a vertical fluted condenser tube based upon condensate film thickness. A marine condenser sizing procedure is demonstrated using this methodology. A comparison is made between a fluted tube condenser and a comparable smooth tube horizontal condenser. Alternative materials are considered and applicability is assessed for submarine use. The results of the analysis indicate that a smaller volume, lighter weight condenser can be designed for marine use. The marine engineer can specify tube length or condensate drainage rate and size the condenser accordingly. Approximately 20 can be saved in volume, and, by using Titanium in place of Copper-Nickel, approximately 30 can be saved in tube bundle weight, compared to a similar horizontal condenser. Author
