Marine Surface Condenser Design Using Vertical Tubes Which Are Enhanced.
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)
