There is no laminar flow in a sax, but there are nodal points where the air molecules move with maximum displacement (and minimum pressure variation) as opposed to nodal points with maximum pressure variation and minimum displacement. Turbulence can affect the air movement and rob efficiency wherever there is a sufficiently sharp discontinuity in the bore, such as at edges of tone holes.In engineering school we learned about turbulent and laminar flow. I wonder if these characteristics influence "resistance."
