...K. Aderogba A spherical drop of viscosity μ ( 1 ) and radius a 1 is surrounded by a spherical shell of viscosity μ ( 2 ) , internal radius a 1 , and external radius a 2 , beyond which there is an unbounded matrix fluid of viscosity μ ( 3 ) . An arbitrary axisymmetric singularity acts inside...

... phases are treated as a single fluid with variable material properties. The front-tracking methodology is combined with a newly developed finite volume solver based on dual time-stepping, diagonalized alternating direction implicit multigrid method. The method is first validated for a freely rising drop...
