Abstract

A method was proposed to augment the forced convection to ambient air from a horizontal rectangular plate with its upper surface mounted with uniformly spaced and heated transverse rectangular ribs. The steady-state effects of varying the penetration ratio (β), diameter of the hole (d), ratio of channel's height to rib's common height (H/B), and Reynolds number (Rec), of the air-flow on the rate of forced convection from the rectangular plate, were investigated for both laminar and turbulent flows over the ribs. Heat transfer measurements were obtained for the ranges: 500≤Re_c≤19,000; 4≤H/B≤10≤0.20.
