The Reynolds number is the ratio of inertial forces to viscous forces in a fluid flow, which governs the local range of turbulent eddy sizes.

THE downstream component of the turbulent velocity has been recorded in a sea-water channel with a Reynolds number, based on the depth, of 4 × 107. The measurements were made near the southern ...

The top of this figure represents the IAG team's large-scale simulation, which captured the complete development of a turbulent boundary layer from low to high Reynolds numbers. As a flow moves ...
