In terms of a dimensionless number, introduced by Arpacı (1986, 1990, 1995) for buoyancy driven flows, Ra and Pr respectively being the usual Rayleigh and Prandtl numbers, two well-known correlations (Churchill and Chu, 1975) for natural convection next to a vertical isothermal plate are reduced in terms of to for the laminar case, and in terms of to for the turbulent case.
