This paper considers a thick liquid film of mean thickness h0 coating the interior surface of a uniformly heated vertical tube of radius a under the influence of gravity (h0 is not far thinner than the radius a). An asymptotic model based on the long-wave assumption is derived. Linear stability anal...
