Dripping instability of a two-dimensional liquid film under an inclined plate

It is known that the dripping of a liquid film on underside plate can be suppressed by tilting so as to cause sufficiently strong flow. This paper uses two-dimensional numerical simulations in closed-flow framework study several aspects this phenomenon. shown that, quasi-equilibrium conditions, onset closely associated with curvature wave crests approaching well-defined maximum value. When dynamic effects become significant, connection between and weakens, although critical remains useful reference point it intimately related short length scales promoted Rayleigh–Taylor instability. In absence flow, when horizontal plate, concept limit relevant only for small volumes close Otherwise, drops form have smaller large volume. The also illustrates peculiarly dependence transition initial conditions simulations. feature prevents development phase maps dependent governing parameters (Reynolds number, Bond etc.) similar those available flow upper side an inclined plate.
