Abstract: The mathematical modeling of the flows that appear in a viscous liquid sessile drop after its equilibrium state is disturbed has been carried out. The free oscillation's frequency and the decay coefficient are obtained for different liquids. The comparison of the numerical results with the analytical theory describing the vibrations of a semispherical free-force drop has been developed.

Keywords: surface tension, sessile droplet, computer simulation.
