Title:NumericalStudyonAerodynamicPerformanceOptimizationofDolphin'sCaudalFinPectoralWingModel
Abstract:
Theaerodynamicinvestigationofbio-inspiredsolutionshasgainedsignificantattentioninrecentyears.Thisstudyfocusesontheoptimizationoftheaerodynamicperformanceofadolphin’scaudalfinpectoralwingmodelusingnumericalsimulations.Theobjectiveistoexplorethepotentialofimprovingtheaerodynamicefficiencyandmaneuverabilityofunmannedaerialvehiclesthroughbio-inspireddesignmodifications.
Introduction:
Naturehasalwaysbeenasourceofinspirationfornoveldesignstrategies,includingthefieldofaerodynamics.Dolphinsareexceptionalswimmers,possessingastreamlinedbodyshapeandauniquecaudalfinpectoralwingconfigurationthatenablesthemtonavigatetheirwateryenvironmentwithremarkableefficiencyandagility.Thisstudyaimstoinvestigatetheaerodynamicpropertiesofabio-inspireddolphincaudalfinpectoralwingmodelandoptimizeitsperformanceusingnumericalsimulations.
