| Abstract: | Numerical analysis of energy-saving mechanism of Propeller Boss Cap Fins and study of performance parameters matching problem in the viscous flow field are based on RANS method. The data points of propeller Boss Cap Fins were calculated by FORTRAN program with specific data format, which were used to set up geometry in Gambit during the modeling phase. The B4-40 standard Propeller is simulated and the results are compared with the tests. The results of special propeller with different blades are compared and the parameter matching problem of PBCF is studied. The corresponding changes of propulsion efficiency are studied on the condition of various diameters and angles of fins, the pressure distribution and wakes are analyzed. The results show that the right size diameter and reasonable installation angle of fins significantly improve its propulsion efficiency and with engineering practicality. |
