Wake energy recovery of a ship’s propeller is an important research subject in ship propulsion field. Based on the study on the mechanism analysis and computation method of the hydrodynamic performance of the propeller-rudder-rudder bubble combination, computer simulation system was built and then used to design and simulate four kinds of rudder bubbles, then the model comparison tests with the original rudder was carried out and the sensible factors influencing the energy-saving effects of rudder bubble was also analyzed. On this basis, a further optimized design of the rudder bubble for a fishing boat was put forward, and comparison test on a real boat was then carried out. It is shown that the optimized rudder bubble design can effectively recover wake energy of ships and the rudder bubble installation features a simple operation and high cost-effectiveness, and the energy-saving effect of real boat test achieves 5.1%. 展开更多
