The Rayleigh number (Ra) is a dimensionless number that represents the ratio of buoyancy forces to viscous forces in free convection, and it is defined as:

ρc_p(DT/Dt) = k∇²T

, which represents the variation of density with temperature at constant pressure. The Rayleigh number (Ra) is a dimensionless number
