Free Convection across Inclined Air Layers with One Surface V-Corrugated

Experimental measurements are presented for free convective heat transfer across incline air layers, heated from below, and bounded by one V-corrugated plate and one flat plate. The measurements covered three values for the ratio, A, (average plate spacing to V-height), namely, A=1,2.5 and 4. It also covered angles of inclination with respect to the horizontal, theta, of 0,30,45 and 60 deg, and a range in Rayleigh number of 10
