摘要
When a film of millimetric thickness h(0) tends to dewet, we expect that a dry patch will grow at a constant velocity, and will be preceded by a 'flat rim' of thickness h*, where h* is exactly the equilibrium thickness, related to the spreading coefficient. The rim front should be identical to a 'shallow water shock'. For liquids of viscosities comparable to that of water, the Reynolds numbers are of order 100, and this inertial regime should be observable.
