Sherwood number Calculator

The Sherwood number () is a dimensionless parameter used in fluid mechanics and heat transfer to characterize the mass transfer rate in a fluid flow system. It represents the ratio of convective mass transfer to molecular diffusion, analogous to the Nusselt number for heat transfer. The Sherwood number can be expressed mathematically as,

Where:

  • is the Sherwood number,
  • is the convective mass transfer coefficient, 
  • is a characteristic length scale of the flow,
  • is the mass diffusivity of the fluid.
