摘　　要：文章介绍在中国船舶科学研究中心大型循环水槽的一集装箱船模型空泡试验中观测到了连体涡空泡(PHVC)。为此,结合三个新设计桨方案和附体(涡流发生器、预旋导轮和伴流补偿导管)开发了四套用于抑制连体涡空泡的措施。其中,三套达到了工程应用的要求。基于这些工作以及在实验室积累的模型试验数据的基础上,提出了水动力相互作用强度因子I_H,并建议I_H≤3.2作为连体涡空泡评判的保守准则。当船舶螺旋桨的进流足够好或者控制得足够好时,可以在I_H>3.2时不发生连体涡空泡。In this paper,the propeller-hull vortex cavitation(PHVC)was observed on a container vessel in the Large Cavitation Channel of CSSRC.Then four vortex-restrained measures were exploited to restrain PHVC using the combination of three new designed propellers and three appendages(vortex generator VG,pre-shrouded vane PSV and wake equaling duct WED).Three of those measures reached the engineering request.According to the above work and accumulated data of ship models,a parameter IHof hydrodynamic interaction intensity was proposed.IH≤3.2 was suggested as a conservative criterion to evaluate the PHVC occurring for further discussion openly.A well designed or controlled inflow of ship propeller permits IH>3.2 without PHVC.
