K
Knudsen number
Knudsen number is the ratio of the molecular mean free path length to a representative physical length scale. It is represented as:
K
Keulegan–Carpenter number
Keulegan–Carpenter number describes the relative importance of the drag forces over inertia forces for bluff objects in an oscillatory fluid flow. It is also known as period number.
I
Iribarren number
Iribarren number is used to model several effects of surface gravity waves on beaches and coastal structures. It is also known as the surf similarity parameter and breaker parameter. While
H
Hagen number
The Hagen number is the forced flow equivalent of the Grashof number. It is represented as:
G
Grashof Number
The Grashof number (Gr) is the ratio of the buoyancy to the viscous force acting on a fluid. In mass transfer, temperatures will be replaced with concentration.
G
Graetz Number
In fluid dynamics, the Graetz number (Gz) characterizes laminar flow in a conduit. It is expressed as: In mass transfer, it is the ratio of momentum diffusivity to mass diffusivity.
G
Görtler Number
Görtler number is the ratio of centrifugal effects to the viscous effects in the boundary layer.
