Sliding of a liquid spherical drop in an external fluid: a generalization of the Hadamard-Rybczynski equation
Peter Lebedev-Stepanov
An analytical solution is obtained for the problem of the slow movement of a small drop of liquid in another immiscible liquid in an infinitely large reservoir with the boundary co…

Sliding of a liquid spherical droplet in an external insoluble liquid at low Reynolds numbers
Peter Lebedev-Stepanov
The experiment shows that small liquid droplets under the action of gravity and the Archimedes force move in the external viscous liquid practically according to the Stokes drag fo…
