Title:ResearchontheHydrodynamicLiftModelfortheReductionofRollMotionbyFinTypeInducedLiftatZeroSpeed
Abstract:
Thispaperfocusesonthestudyofhydrodynamicliftmodelsforreducingtherollmotionofvesselsatzerospeedusingfin-inducedlift.Theaimofthisresearchistoexploretheeffectivenessofvariousfintypesingeneratingliftandthecorrespondingreductionofrollmotionforstationaryvessels.Theresearchfindingscontributetotheunderstandingofthehydrodynamicsinvolvedinreducingrollmotionatzerospeed,andprovidevaluableinsightsforthedesignandoptimizationofshipstabilizers.
1.Introduction:
Shipmotionduringseakeeping,especiallyrollmotion,canhavesignificantimplicationsforoperationalefficiency,comfort,andsafety.Whilefinstabilizershavebeenwidelyadoptedinshipdesignstoreducerollmotion,theireffectivenessatzerospeedremainslessexplored.Theobjectiveofthisresearchistoinvestigatethehydrodynamicliftmodelsinducedbyvariousfintypestomitigaterollmotionatzerospeed.
2.LiteratureReview:
Previousstudieshaveexploredtheeffectofdifferentfinconfigurationsonrollmotionreductionundervariousoperationalconditions.However,fewhavespecificallyfocusedonzero-speedscenarios.Somestudieshaveinvestigatedthehydrodynamicsinvolvedinliftgenerationbyanalyzingtheinteractionbetweenthefinandthesurroundingwater.Thesetheoreticalanalyses,alongwithempiricalfindings,provideafoundationforfurtherresearch.
