摘要： With the 42m trawler as object, an ordinary propeller and a ducted propeller are designed and their open water hydrodynamic performance are simulated by using CFD software. The computed results and experimental results of ducted propeller are in good agreement, which verified the reliability of numerical calculation. Then the computed results of ordinary propeller and ducted propeller are compared with each other, it is found that the thrust and torque of ducted propeller is bigger than ordinary propeller in trawling. This article also discusses the pressure distribution of their blade and the reason why ducted propeller has a better hydrodynamic performance is studied.
