Flux Richardson Number Definition
The Flux Richardson number (Rif) is a dimensionless number used in fluid dynamics to represent the ratio of forces acting on a fluid parcel.
Specifically, it compares the contribution of buoyancy to the contribution of mechanical forcing (like wind or stirring) in influencing fluid motion or turbulence.
Definition:
- Flux Richardson Number =
(Buoyant Production) / (Mechanical Production)
Where:
- Buoyant Production refers to the generation of kinetic energy (or turbulence) due to density differences (buoyancy).
- Mechanical Production refers to the generation of kinetic energy (or turbulence) due to mechanical stirring or shear forces.
A higher Flux Richardson number indicates that buoyancy forces are dominant, while a lower number suggests mechanical forces are more significant.
