8.8 Flow instability and vortex shedding

If a velocity profile contains an inflection point (i.e. if the velocity gradient changes sign), then it will be convectively unstable, unless the Reynolds number is low. If a velocity profile contains two shear layers, as in the wake behind a bluff body, then it will be absolutely unstable, unless the Reynolds number is low. This absolute instability causes vortex shedding.

Sir which book is good for flow and thermal instability
