    • Abstract

       

      Some recent developments in boundary layer instabilities and transition are reviewed. Background disturbance levels determine the instability mechanism that ultimately leads to turbulence. At low noise levels, the traditional Tollmien-Schlichting route is followed, while at high levels, a ‘by-pass’ route is more likely. Our recent work shows that spot birth is related to the pattern of secondary instability in either route.
