Roshko number, abbreviated as Ro, a dimensionless number, is describing oscillating flow mechanisms.


Formulas that use Roshko Number

\(\large{ Ro =  \frac{ f \; l_c^2 }{ \nu }  }\)   


\(\large{ Ro }\) = Roshko number

\(\large{ l_c }\) = characteristic length

\(\large{ f }\) = frequency of vortex shedding

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