【摘要】 针对导管螺旋桨这类组合式推进器的设计问题,采用了粘流CFD与传统的势流升力面设计相耦合的方法来计算,以此来考虑船体及其附体与推进器的相互作用,以及流场粘性的影响,解决设计所需的实效进流场的问题,并采用此方法作了导管螺旋桨的设计和模型试验。更多还原

【Abstract】 A ducted propeller design method and process were presented,which coupling RANS method and lifting surface design method to get effective wake and to design ducted propeller.Ship hull,appendages,duct and propeller were considered as an integrated system of bodies and RANS code was employed to predict the total effective inflow to the propeller inside the duct.The method is finally validated by experiment.The results show that it is valulable.更多还原
