ABSTRACT

An experimental investigation of heat transfer in an inclined (φ = 30°, 60°) flat channel with one-sided heating (the upper wall is heated) for opposing turbulent mixed-convection flow conditions have been performed in the region of Re = 4·103−4·104, Grq = 1.7·108− 1.4·1010 . The obtained data were compared with the results obtained in the vertical channel.
