Isi artikel

In terms of a dimensionless number, N ~ Ra / (1 + Pr(–1)), introduced by Arpac(1) (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 II(L) = Ra / (1 + 0.492 Pr (– 1)) to Nu = 0.67 II L (1/4) , 10(3) <= IIL <= 10(9), for the laminar case, and in terms of II(T) = Ra / (1 + 0.164 Pr(–1)) to Nu = 0.15 II(T) (1/3) , 10(9) <= T <= 10(12), for the turbulent case.
