The Rayleigh Number (Ra) is a measure of the strength of the conduction or convection as mechanisms of transfer of energy. This same equation is often used in Geosicence / Atmospheric Sciences.
Conduction is the transfer of energy between objects that are in physical contact and convection is the transfer of energy between an object and its environment due to motion of fluids or gases.
The inputs to this equation are:
- g = gravitational acceleration
- rho = the density difference
- mu = dynamic viscosity
- L = length
- alpha = thermal diffusivity
