Schmidt Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Schmidt number, abbreviated as Sc, is a dimensionless number in fluid mechanics used in analyzing fluid flows where there is an interface between two different fluids. 

Schmidt Number formula

\(\large{ Sc =   \frac{  \nu }{  D_m  }    }\)         

\(\large{ Sc =   \frac{  \mu }{ \rho \; D_m  }    }\)         

Where:

\(\large{ Sc }\) = Schmidt number

\(\large{ \rho }\)  (Greek symbol rho) = density

\(\large{ \mu }\)  (Greek symbol mu) = dynamic viscosity

\(\large{ \nu }\)  (Greek symbol nu) = kinematic viscosity

\(\large{ D_m }\) = mass diffusivity
