The Formation and Growth of a Hairpin Vortex

  • Bart A. Singer
Part of the ICASE NASA LaRC Series book series (ICASE/NASA)


Direct numerical simulation was used to study the formation and growth of a hairpin vortex in a flat-plate boundary layer. Fluid injection through the wall initiated a vortex which then spawned secondary and tertiary vortices before viscosity damped the disturbance. A second simulation in which the blowing was much weaker, but extended over a larger streamwise distance did not produce a hairpin vortex.
