A method for full numerical simulations of unsteady, incompressible Navier-Stokes equations for multi-fluid systems is developed. Moving interfaces between dissimilar fluids are explicitly tracked and fluid properties are constructed on a stationary grid using the position of the interfaces. The emphasis is on the shape regimes of bubbles and bubble-bubble interactions in a stationary fluid. The Rayleigh-Taylor instability is also studied. Weak and strong density stratification and the effect of viscous stratification on the growth of fingers is investigated. Interaction of a vortex pair with a density interface is briefly studied.
