Dimensionless quantity characterising the development of Natural Thermal Convection:
| (1) | \mbox{Gr} = \frac{g \, \beta \, \Delta T \, L^3}{\nu^2} |
where
\Delta T | temperature gradient |
|---|---|
\beta | Thermal expansion coefficient |
L | characteristic length |
\nu | Kinematic viscosity |
g | Standard gravity constant |
