Abstract：Ceramicmatrixcomposites(CMCs)areoneofthemostpromisingmaterialsinthefieldofgasturbines,withsuperiorweightandthermalproperties.Itssurfacemorphologyisdifferentfromthetraditionalcastingairfoilcomponents,whichmainlycomesfromdifferentweavingmethodsanddifferentbraidedtowthickness.However,fewpeoplehavestudiedtheinfluenceofsurfacemorphologyofceramicmatrixcomposites(CMCs)onthedevelopmentofboundarylayerandtheresultingflowloss.Inthispaper,TexGenisusedtogeneratedifferentsurfacemorphologystructuresofceramicmatrixcomposites(CMCs),andthesurfaceflowcharacteristicsofcorrespondingCMCsplatesarenumericallystudied.Itisfoundthattheslopeofthedisplacementthicknessofthewovensurfacefirstincreasesandthendecreasesinthewholetransitioninterval.Thickerbraidedtowthicknessanddenserbraidingmethodwillinduceearlierflowtransitionphenomenonandproducegreaterflowloss;TheflowlossonthesurfaceofCMCsplateismainlycomposedofthevortexlossinthepitandtheboundarylayerlossoutsidethepit,andtheboundarylayerlossisdominant.Theweavingmethodshasagreaterinfluenceontheflowstateandflowlossoftheboundarylayer.
