| Abstract | Stern flaps are appendages attached to the transom of a vessel which can decrease resistance at some speeds. This can translate to significant fuel savings when applied to a fleet of similar ships. A recent study investigating a stern flap design for the Canadian Navy's HALIFAX Class frigates showed a significant sensitivity to trim angle at high speeds. Further exploration on the role of trim angle was conducted using CFD simulations for three naval combatants: the Canadian HALIFAX Class, the U.S. CG-47/DD-963, and the U.S. DDG-51. The CFD simulations were validated against model test data for each hull type, and then used to determine the role of trim angle in resistance reduction from stern flaps. |
