后置导叶对斜流泵性能影响的分析的中期报告 Dearsupervisors, Iamwritingtoprovideamid-termreportonmyanalysisoftheimpactofaftguidevanesontheperformanceofdiagonalflowpumps. Tobeginwith,Ihaveconductedathoroughliteraturereviewandcollectedasignificantamountofdataonthetopic.Myresearchhasshownthataftguidevanescanhaveapositiveimpactontheperformanceofdiagonalflowpumpsbyreducingrecirculationandimprovinghydraulicefficiency.However,thedegreeofimpactvariesdependingonavarietyoffactorssuchasthedesignofthepump,thespecificgeometryofthevanes,andthefluidproperties. Next,Ihaveusedcomputationalfluiddynamics(CFD)simulationstomodeltheflowbehaviorwithindiagonalflowpumpswithandwithoutaftguidevanes.Byanalyzingtheresultingdata,Ihavebeenabletodrawsomepreliminaryconclusionsabouttheimpactofthevanesonpumpperformance.Specifically,Ihavefoundthattheadditionofaftguidevanescanreducethesizeandintensityofvortexstructureswithinthepump,thusleadingtoimprovedefficiency.However,Ihavealsoobservedthattheimpactofthevanesontheflowbehaviorishighlydependentontheirplacementandorientationwithinthepump.
