A sharp-diffuse interface model for intermittent and isolated topological transitions
Raaghav Ramani
We propose a hybrid sharp-diffuse interface representation for modeling intermittent and isolated topological transitions during Cahn-Hilliard phase coarsening. Away from topologic…

A multiscale model for Rayleigh-Taylor and Richtmyer-Meshkov instabilities
Raag Ramani, Steve Shkoller
We develop a novel multiscale model of interface motion for the Rayleigh-Taylor instability (RTI) and Richtmyer-Meshkov instability (RMI) for two-dimensional, inviscid, compressibl…
