On the flux Richardson number in stably stratified turbulence

SK Venayagamoorthy, JR Koseff - Journal of Fluid Mechanics, 2016 - cambridge.org
The flux Richardson number $ R_ {f} $(often referred to as the mixing efficiency) is a widely
used parameter in stably stratified turbulence which is intended to provide a measure of the …
