BYPASS TRANSITION AND SUBCRITICAL TURBULENCE IN PLANE POISEUILLE FLOW
BYPASS TRANSITION AND SUBCRITICAL TURBULENCE IN PLANE POISEUILLE FLOW
Plane Poiseuille flow shows turbulence at a Reynolds number that is lower than the critical one for the onset of Tollmien-Schlichting waves. The transition to turbulence follows the same route as the by-pass transition in boundary layers, i.e. finite amplitude perturbations are required and the flow is dominated by downstream …
