This paper reports on an opposing flow of turbulent combined forced and natural convection along a vertical flat plate heated with a uniform heat flux that was investigated experimentally. The local heat-transfer coefficients along the vertical direction were measured at high Rayleigh and Reynolds numbers. It was found that the heat-transfer rates in the combined convection region became much larger than those for both the pure forced and pure natural convection. The natural, forced, and their combined convection regions are classified in terms of the nondimensional parameter, {zeta} = (Gr{sub x}*/Nu{sub x}Re{sub x}{sup 2.7}). These results are then compared with those for aiding flow.
