Transition to Turbulence

Smoke introduced into the boundary layer of a cone rotating in a stream highlights the transition from laminar to turbulent flow. On the left side of the picture, the boundary Keep reading

Osborne Reynolds and Transition

How and when flow through a pipe becomes turbulent has been a conundrum for fluid mechanicians since the days of Osbourne Reynolds (~1870s): Typically, the laminar-to-turbulence transition is studied mathematically Keep reading
