Numerical Methods for Fluid-Solid Coupled Simulations: Robin Interface Conditions and Shock-Dominated Applications
… to implement the Robin interface condition in an embedded boundary method for coupling a parallel, projection-based incompressible viscous flow solver with a nonlinear finite element solid solver. Both an analytical study and a numerical study reveal that the new algorithm can clearly outperform …

Multiphysics algorithms for the simulation of geological materials under extreme conditions: the evolution and transport of ablated material
… upwards of 106 particles, it follows that a method which considers particles and fluid as interpenetrating continua is the natural choice. Unfortunately, there exist a large number of continuum gas-solid models in the literature, which do not necessarily agree with each other. To eliminate …

Long-Pulsed Laser-Induced Cavitation: Laser-Fluid Coupling, Phase Transition, and Bubble Dynamics
This dissertation develops a computational method for simulating laser-induced cavitation and investigates the mechanism behind the formation of non-spherical bubbles induced by long-pulsed lasers. The proposed computational method accounts for the laser emission and absorption, phase transition, …
