Richardson Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Richardson number, abbreviated as Ri, a dimensionless number, is the ratio of the buoyancy term to the flow shear term.

 

Richardson Number formula

\(\large{ f = \frac{ Gr }{ Re^2 }  }\)   

Where:

 Units English Metric
\(\large{ Ri }\) = Richardson number \(\large{dimensionless}\)
\(\large{ Gr }\) = Grashof number \(\large{dimensionless}\)
\(\large{ Re }\) = Reynolds number \(\large{dimensionless}\)
