What is Schmidt number in Fluid Mechanics ? How is Schmidt number calculated ?

Schmidt number, which is denoted as Sc, is a dimensionless number defined as the ratio of momentum diffusivity and mass diffusivity. Schmidt number is used to characterize fluid flows in which there are simultaneous momentum and mass diffusion convection processes.

What does Schmidt number mean ?

Schmidt number is a dimensionless number used in mass transfer. It is expressed as the ratio of momentum and mass diffusion coefficients to each other.

What is Schmidt number in Fluid Mechanics ?

Schmidt number is a dimensionless number defined as the diffusion coefficient, the ratio used to define kinematic viscosity and the same acceleration diffusion and mass diffusion as the liquid. The number of Schmidt was named in honor of the German engineer Ernst Heinrich Wilhelm Schmidt (1892-1975).

ν is kinematic viscosity coefficient

D is the diffusion coefficient.

μ is viscosity coefficient

ρ is the density

How is Schmidt number defined for laminar flow ?

For transport and mass transfer in laminar flows, the number Sc indicates the ratio of the thicknesses of the speed and concentration boundary layers to each other.

What is the definition of Schmidt number in scientific terms ?

Schmidt number is a dimensionless number which is the ratio of momentum diffusivity to mass diffusivity (or) velocity boundary layer to concentration boundary layer. It is used to characterize flows when there is simultaneous momentum and mass transfer.
