Transition to Turbulence Series – Transition Scenarios

Motivation: There are various type of instabilities for a number of flow patterns. The intention of this post is to investigate how these instabilities may trigger laminar-turbulent transition. I shall do my best to classify these routes leading from a stable laminar to a disturbed one flow, and base my path on the mechanisms responsible …

Nonmodal instability of PDE discretizations – Spectra Analysis – An Introduction Primer for ByPass Transition

In this section we're going to pull out a few tools from our analysis arsenal and pay very close attention to what might seem at first like odd results. Doing that would be best on well known basic flows, i.e. Plane Poiseuille, and then Blasius boundary layer, pipe flow and coutte. Plane Poiseuille It is …
