Abstract

Motion of an inclined plate supported by a two-dimensional sessile drop on a second plate is studied in the inertialess approximation. It is shown that the upper plate can be equilibrated horizontally, parallel to the lower plate supporting the drop, when the Bond number exceeds a certain threshold value. The dependence of this threshold value on the parameters of the plate and liquid is found and discussed. Small oscillations of the plate near its equilibrium horizontal position on top of the drop are investigated analytically in the case of low liquid viscosity. The periods of the vertical (translational) and angular oscillations are determined. Comparison with experimental data demonstrates reasonable agreement between the characteristic times of the process predicted analytically and observed experimentally.
