Archimedes Number

Archimedes number is proportional to { (gravitational force) / (viscous force) } and is used in momentum transfer in general and buoyancy, fluidization, and motion due to density difference calculations in particular. It is normally defined in the following form :

 

Archimedes Number

 

Where:

g

=

Gravitational acceleration

L

=

Characteristic length

mu

=

Viscosity

rho_f

=

Fluid density

rho_s

=

Solid density
