Galileo Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Galileo number, abbreviated as Ga, is a dimensionless number used in fluid dynamics to describe fluid film flow over walls.  It is a ratio of forces present in the flow of viscous fluids.  The Galileo Number is used in the momentum of heat transfer, viscous flow, thermal expansion.

Galileo number formula

\(\large{ Ga = \frac{ g \;  l^3 \;  \mu^2 } { \rho^2 } }\)   

Where:

\(\large{ Ga }\) = Galileo number

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

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

\(\large{ g }\) = gravitational acceleration

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