This progress report covers our work over the last grant period (1990-1993). Work has been in the following areas: semi-analytical studies of enhanced energy transport in natural convection due to time dependent body forces; large scale simulations of non-linear instabilities in porous media flow for situations of interest in petroleum recovery; analytical studies of `chimney` formation in unstable freezing mixtures; analytical and experimental studies of contact line dynamics for Newtonian and non-Newtonian fluids; and large scale numerical simulations of shear instabilities of viscoelastic fluids
