"A numerical model of drop dynamics of viscous liquid"
Maikov I.L., Director L.B.

On the basis of the level set function method, a numerical model of viscous liquid dynamics is proposed to describe the processes of nonlinear drop oscillations during free falling, impact with a horizontal surface, breaking up, and merge of liquid drops in an immiscible fluid. Solutions for fluids with the characteristic density ratio less than 0.001 and Re>1000 are obtained. The results of modeling the process of drop falling are compared with available numerical and experimental data.

Keywords: mathematical modeling, viscous liquid, level set function, Plato sphere, free surface
