Multiphase flows and plasmas

Direct simulations (gas/liquid/solid compressible Navier-Stokes) and simple models (Rayleigh-Plesset) are used to understand bubble dynamics and the damage thereby produced, as well as droplet dynamics.

Target applications include medicine (diagnostic/therapeutic ultrasound, traumatic brain injury, wound healing), naval hydrodynamics (cavitation erosion), hypersonics, energy sciences (nuclear energy, Spallation Neutron Source).
