Abstract
The paper reports a series of DNS, LES and experimental studies of unsteady flows following a sudden increase in flow rate from an initial turbulent flow in a channel with smooth or rough surfaces and shows that the transient flow is laminar-turbulent transition even though the initial flow is turbulent.
