From Wacklepedia - The Free Encyclopedia
The
Sherwood number (Sh) is a
dimensionless number used in mass-transfer operation. It represents the ratio of lengthscale to the diffusive
boundary layer thickness.
It is defined as follows
It is the mass-transfer equivalent of the Nusselt number
where
- = overall mass transfer coefficient;
- = characteristic length;
- = component diffusion coefficient
