CAVITATION AROUND PROPELLERS EQUIPPED WITH ENRGY SAVING DEVICES

The main focus of this article is the development and use of clean renewable energy sources – energy saving devices, on ships. These mechanisms improve the propulsion performance and lower the fuel consumption of the ship using reaction fins for low-speed full ships and stator fins for high-speed slender ships. By using CFD - fluid flow computer program, we analyzed and evaluated the cavity propellers on ships equipped with energy-saving mechanism, including keel and rudder. This helps in understanding the flow characteristics such as pressure distribution on the propeller that would otherwise require many hours of effort and experimental analysis. The result is a high degree of propeller optimization and of the mechanism with the role of energy saving. The main reason of this article is to try to reduce cavitation around the propeller and show a modality for reducing ship pollution, so the quantity of fuel used, that mince, to reduce the price of transportation and it becomes a method of saving money for the ship owners and charters.
