Marine surface condenser design using vertical tubes which are enhanced.
marinesurfacecon00barn.pdf (7.082Mb)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 result of the analysis indicate that a smaller volume, lighter weight condenser can be designed for marine use. The marine engineer can specific tube length of condensate drainage rate and size the condenser accordingly. Approximately 20% can be saved in volume, and, by using Titanium instead of Copper/Nickel, approximately 30% can be saved in tube bundle weight, compared to a similar horizontal condenser.
