Classical model dealing with free oscillations and damping of droplets without gravity cannot correctly describe the correspondence between measured damping coefficient and viscosity.

An energetic approach taking into account the flattened shape of the drop, the particular boundary conditions imposed by the set-up, and the velocity field of the liquid inside the drop, is introduced, leading to good agreement between experimental measurements and known viscosities of calibrated liquids.
