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 across Natural Thermal Convection | \nu | Kinematic viscosity of the fluid |
|---|---|---|---|
\beta | Thermal expansion coefficient of the fluid | g | Standard gravity constant |
L | Characteristic length of Natural Thermal Convection |
