State-Of-The-Art CFD calculations for the propeller fitted on a vessel Wärtsilä Energopac system with FPP bronze alloys for marine propellers, the most commonly used being Cunial® bronze. This copper, nickel, and aluminium alloy has unparalleled durability and reliability. Casting is an extremely complex procedure, and in order to assure a successful casting process, solidification simulation software is used for the more difficult geometries. The propellers can be produced with any required number of blades in diameters up to 12 meters. Both the propellers and shaft lines are designed to meet...

Fixed Pitch Propeller in HP nozzle Wärtsilä Built-Up Propeller. Example of stainless steel application for heavy ice class RoPax. Propeller with regular cap Propeller with EnergoProFin Cavitation observations for same propeller with and without EnergoProFin l The Wärtsilä EnergoProFin is an innovative propeller cap with fins that rotates together with the propeller. By weakening the hub vortex, resistance is decreased and propulsion thrust is increased, resulting in average fuel savings of 2%. l Energopac is Wärtsilä’s optimised propulsion CFD computed pressure distribution on a Tip Rake propeller and...
