Heat transfer in the flow of a cold, two-dimensional draining sheet over a hot, horizontal cylinder

The paper considers heat transfer characteristics of thin film flow over a hot horizontal cylinder resulting from a cold vertical sheet Of liquid failing onto the surface. The underlying physical features of the developing film thickness, velocity and temperature distributions have been illustrated by numerical Solutions Of high accuracy for large Reynolds numbers using the modified Keller box method. The Solutions for film thickness distribution are good agreement with those obtained using the Pohlhausen integral momentum technique thus providing a basic confirmation of the validity of the results presented.
