Research

Roman Samulyak holds a joint appointment at the AMS Department, Stony Brook University and Computational Science Center, Brookhaven National Laboratory. His research interests include mathematical modeling and numerical algorithms for coupled systems of PDE equations for multiphase systems and applications to the simulations of  physics processes in particle accelerators, nuclear fusion and fission devices, and atmospheric / climate systems. He has developed models and numerical algorithms for multiphase hydro and magneto-hydrodynamic flows with phase transitions, electromagnetic systems etc. using methods of front tracking and imbedded boundaries. His latest research interests include mesoscale models for brittle fracture and smooth Lagrangian particles methods for hydro and MHD problems.

Current research projects:

• Plasma Jet Driven Magnetoinertial Fusion
  
• Pellet Fueling of Thermonuclear Fusion Devices
• Magnetohydrodynamics of Multiphase Systems
• Liquid Mercury Targets for Future Accelerators
• Mesoscale models for brittle fracture
