Pipe Flow Turbulence

The unexpected connection between brewing coffee and understanding turbulence

A team of researchers led by Nigel Goldenfeld and Björn Hof used statistical mechanics to study turbulence in fluid flows. They discovered that the transitions between laminar and turbulent flows occur through a non-equilibrium phase transition, known as directed percolation, at the critical point of the transition.

Pumping like the heart

Researchers found a 27% decrease in mean friction and a 9% reduction in energy demand through pulsating pumping similar to the human heart. This approach could lead to less costly modifications than pipe wall changes or actuators, benefiting industrial applications.
