Vadasz Number

Tags: Soil

Vadasz number, abbreviated as Va, a dimensionless number, governs the effect of porosity on flow in a porous media.

 

Vadasz Number formula
\(\large{ Va =  \frac { \phi \; Pr }{ Da } }\)
Symbol	English	Metric
\(\large{ Va }\) = Vadasz number	\(\large{ dimensionless }\)
\(\large{ \phi }\)  (Greek symbol phi) = porous media	\(\large{ dimensionless }\)
\(\large{ Pr }\) = Prandtl number	\(\large{ dimensionless }\)
\(\large{ Da }\) = Darcy friction factor	\(\large{ dimensionless }\)
