Landau and Levich split the entire flow regime into two regimes, a lower regime and an upper regime. In the lower regime closer to the liquid surface, the flow is assumed to be static, leading to the problem of the Young–Laplace equation (a static meniscus). In the upper region far away from the liquid surface, the thickness of the liquid layer attaching to the plate is very small and also the since the velocity of the plate is small, this regime comes under the approximation of lubrication … Tīmeklisand Frankel6 for soap films and by Landau, Levich and Der-jaguin10,11 for coated films. Both models assume the fluid properties to be independent of position and, using the Stokes equation combined with suitable boundary conditions, they yield the same scaling law for the thickness h 0 of a film gen-erated at a constant velocity V : …
