Abstract
Transition to turbulence, possibly followed by a relaminarization process, remains one of the most intriguing features found in many fluid flows. It is at the same time a highly relevant process for practical applications, since it will suddenly impact drag losses (along an aircraft wing), mixing properties (within a static mixer) or shear forces acting on cells (in a tubular bioreactor), to name just a few such cases.
