WebAt higher Grashof numbers, the boundary layer is turbulent; at lower Grashof numbers, the boundary layer is laminar. The product of the Grashof number and the Prandtl number gives the Rayleigh number, a dimensionless number that characterizes convection problems in heat transfer. Webwhere Gr≡gL 3 β H ΔT/v 2 is the Grashof number for heat transfer. Here β H =1/T for …
