  • The lifetimes of injected jet puffs are used to determine the critical point at which turbulent pipe flow is sustained. Shear flows undergo a sudden transition from laminar to turbulent motion as the velocity increases, and the onset of turbulence radically changes transport efficiency and mixing properties. Even for the well-studied case of pipe flow, it has not been possible to determine at what Reynolds number the motion will be either persistently turbulent or ultimately laminar. We show… CONTINUE READING
