Dean Number

Dean number is proportional to { (Re . centrifugal force) / (inertial force) } and is used in momentum transfer in general and flow in curved channels calculations in particular. It is normally defined in the following form

 

De = (D.V.rho/mu)

 

Where:

D

=

Diameter

L

=

Length

mu

=

Viscosity

R

=

Radius of curvature of bend

rho

=

Density

V

=

Velocity
