AB  - We are concerned about effect of a 3D surfaceindentation on instability and laminar-turbulenttransition   in   a   boundary   layer.  For   naturaltransition  in a boundary layer, the transitiononset is dominated by growth of the Tollmien-Schlichting   (TS)   wave   and   its   subsequentsecondary instability. In the paper, both linearanalysis and nonlinear calculations are carriedout to address the 3D surface indentation effecton   amplifying   TS   waves’   amplitudes   andprompting   transition   onset.   By   the   linearanalysis, we address sudden amplification of theTS modes by a separation bubble in a surfaceindentation region. The nonlinear calculationsare   implemented   to   validate   the   traditionaltransition criteria predicted by the linear theorywhen   a   3D   indentation   is   present.   Finally,applicability   of   the   traditional   transitioncriteria is assessed.
