双流道叶轮三维逆向水力设计方法研究
Project Number51466008

Abstract双流道叶轮的传统设计方法是基于一元理论的速度系数法。由于双流道叶轮的特殊形状,借鉴自叶片式叶轮的设计方法并不完全适用。采用传统方法设计时,会出现绘型图和制作木模的不一致,虽经许多学者指出,但目前尚未提出相对完善的解决办法。相比之下,叶片式离心泵的水力方法则发展很快,相关的文献也很多。本项目拟以双流道叶轮的水力设计方法研究为立足点,旨在完善和解决传统一元设计方法的缺陷,在此基础上对双流道叶轮三维逆向水力设计方法进行研究,并在相关研究成果的基础上,开发叶轮的三维参数化设计程序,将叶轮的水力设计和三维造型结合起来,实现CAD设计和CFD分析的接口,为提高叶轮的设计质量和效率提供方便。【英文摘要】Traditionaldesignmethodofdoublechannelrunnerisbasedonthevelocitymodulusmethodofmon-dimension.Owingtothespecialshapeofdoublechannelrunner,dedignmethodinheritedfrombladetyperunnerisnotverysuitedforit.Ifimplingthetraditionmethod,theinconcidencebetweenchartsofmodelandwoodformerformanufacturewouldoccur.Theproblemwasfoundbymanyscholars,butresolvingmethodisnotyetfound.Comparingthisconfusingconditionofdoublechannelrunner.Centrifugalpumpofbladeshapedevelopedquicklyinhydraulicdesignmethod,withplentyofrelativelyliteratures.Thisapplictionprojectaimsatthehydraulicdesignmethodofdoublechannelrunner,tryingtoimproveandsolvedefectoftraditionmethod,anddevelopathree-Dimensionreversehydraulicdesignmethod,andprogramingcodestodesigntherunnerwithparametersinCADsoftware.Thiswillunitesthehydraulicdesignandthreedimensionshaping,andcanimplementainterfaceofCADandCFD,andbeavailbleforimprovingqualityandefficencyofrunnerdesign.
