Abstract The article studies axisymmetric forms of drop relative equilibrium on a rotating disk due to the action of gravitational, centrifugal and capillary forces. It is obtained that there are two main types of forms of equilibrium: with simply connected and not simply connected sets of points of contact of liquid and solid phases. A number of statements about these forms of equilibrium are proved analytically. The findings are consistent with the numerically found drop shapes for various examples of the input data. Curves for determination of dependencies between various parameters of liquid volume in relative rest are constructed.
Keywords
