The motion of the interface between two Auids in a quasi-two-dimensional geometry is studied via simulations. We consider the case in which a zero-viscosity Quid displaces one with finite viscosity and compare the interfaces that arise with zero surface tension with those that occur when the surface tension is not zero. The interface dynamics can be analyzed in terms of a complex analytic function that maps the unit circle into the interface between the Auids. The physical region of the domain… CONTINUE READING
