On the laminar solutions and stability of accelerating and decelerating channel flows

AJ Linot, PJ Schmid, K Taira - Journal of Fluid Mechanics, 2024 - cambridge.org
We study the effect of acceleration and deceleration on the stability of channel flows. To do
so, we derive an exact solution for laminar profiles of channel flows with an arbitrary, time …
