Abstract
Mathematical formulations for three distinct systems which involve viscous free surface flows are presented. The first model describes boundary conditions posed at a moving contact line formed at the tri-junction of a gas/liquid/solid system. In particular the unification of mass flux conditions is highlighted. The second and third models are solidification systems. Formulations of both models examine the use of asymptotic methods to isolate a mathematical description of the free solidifying surface. In one case evolution equations for solidifying fronts are developed. These equations allow one to investigate micro scale morphology of the interface. In the other model, the influence of macroscopic heat, mass, and momentum transport on the solidifying front is examined. A reduced model is developed which is simpler for analysis yet retains the relevant physics.
