Summary

The waves, which have amplitude of the order of the film substrate, were observed in the region of Reynolds number between 200 and 455, and the heat transfer coefficient is increased by about 60%, while it is identical with the Nusselt theory at Reynolds smaller than 120. In this simulation range the enhancement of the heat transfer is attributed to the decreasing time averaged film thickness due to waves, and the disturbance effects of the waves are small.
