Abstract
The temperature profiles over the cross sections of vertically flowing films of water and aqueous solutions have been directly measured. It is shown that even in the wall boundary layer heat is transported not only by molecular heat conduction but also as a result of the mixing action of the waves, which increases with increase in flow density and film path.
