Analysis of bypass transition process using large eddy simulations

Résumé

This paper describes the setup of a wall-resolved large eddy simulation (LES) of bypass transition on a realistic flat plate and the results obtained. This simulation is the first to compute a bypass transition flow on a flat plate from the receptivity stage to the laminar-turbulent transition onset. The key mechanisms of bypass transition are highlighted by the simulation: the shear-sheltering, the birth of Klebanoff-modes, their amplification, and destabilization.
