Title:NumericalandExperimentalStudyofAerodynamicandHydrodynamicEffectsonHigh-speedCatamaransinCalmWater
Abstract:
High-speedcatamaransaresleekandefficientvesselsthatprovideastableplatformforvariousmarineoperations.Understandingtheaerodynamicandhydrodynamiceffectsonthesevesselsiscrucialforoptimizingtheirperformance,ensuringtheirsafety,andimprovingtheiroveralldesign.Inthisstudy,weinvestigatethenumericalandexperimentalaspectsoftheseeffectsonhigh-speedcatamaransincalmwaterconditions.
Introduction:
High-speedcatamaranshavegainedsignificantattentioninrecentyearsduetotheirstability,efficiency,andversatility.However,theuniquenatureoftheirdesignposeschallengesintermsofunderstandingandmitigatingtheaerodynamicandhydrodynamiceffectsonthesevessels.Thisstudyaimstobridgethisknowledgegapbyconductingbothnumericalsimulationsandexperimentalteststocomprehensivelyanalyzetheseeffectsandtheirimplicationsontheperformanceofhigh-speedcatamaransincalmwaterconditions.
NumericalSimulation:
Thenumericalsimulationisconductedusingcomputationalfluiddynamics(CFD)software,whichusesNavier-Stokesequationstomodelthefluidflowaroundthecatamaranhulls.Thissimulationallowsustounderstandtheflowcharacteristics,pressuredistribution,anddragforcesonthevessel.Theeffectsofvariousparameters,suchashullshape,speed,andangleofattack,areinvestigatedthroughparametricstudies.
ExperimentalTesting:
