If you have a question about this talk, please contact nobody. ADIW04 - Anti-Diffusion in Multiphase and Active Flows The Rayleigh-Taylor instability (RTI), involving the mixing of a heavy fluid over-laying a lighter, occurs in many situations including laboratory tank and fusion experiments, astro-physical phenomena and multi-phase physics. The approach taken by different schools varies widely. We will briefly review these and then spend the next part discussing the Variable Density Model (VDM) for miscible flows pioneered by Cook and Dimotakis (2001) and Livescu and Ristorcelli (2007). The resulting PDEs, while elegantly coupled to the Navier-Stokes equations, pose severe technical challenges. Finally, in joint work with Nairita Pal, Anupam Gupta and Rahul Pandit, I will also discuss the occurrence of the RTI at immiscible interfaces in multi-phase physics which involves the coupling of the Cahn-Hillard equations to the Navier-Stokes equations This talk is part of the Isaac Newton Institute Seminar Series series.
