The Rayleigh number, shown below, is a dimensionless number that characterizes convection problems in heat transfer. A critical value exists for the Rayleigh number, above which fluid motion occurs. The ratio of the Grashof number to the square of the Reynolds number may be used to determine if forced or free convection may be neglected for a system, or if there's a combination of the two. … WebTo use this online calculator for Local Nusselt number given Grashof number, enter Local Grashof Number (Gr x) & Prandtl Number (Pr) and hit the calculate button.
