Sherwood number

Sherwood number

The Sherwood number, mathrm{Sh} (also called the mass transfer Nusselt number) is a dimensionless number used in mass-transfer operation. It represents the ratio of convective to diffusive mass transport, and is named in honor of Thomas Kilgore Sherwood.

It is defined as follows

mathrm{Sh} = Km*L / D

where
* L is a characteristic length
* D is diffusivity (specify!)
* k is the mass transfer coefficient
