Experimental investigation of heat transfer from a horizontal flat surface to aqueous foam flow

An experimental investigation of the heat transfer between a horizontal flat surface and longitudinal foam flow was performed and the results are presented and discussed in this paper. It was observed that the particles of drained liquid film moved in the same direction as the foam flow. The cross-sectional velocity distribution of the foam bubbles influenced on the amount of draining liquid across the channel. Higher inflow of draining liquid of lower temperature gave rise to better conditions for the cooling of the side parts of the heated surface.
