Welcome
I'm a PhD candidate at Oregon State University studying applied and computational mathematics. My research interests are in studying physical phenomena of fluid flow and transport for energy and environment related applications in response to climate change. My dissertation entitled "Multiphase flow and transport in porous media with phase transition at multiple scales," includes the first numerical stability analysis of reduced models for methane gas transport in the subsurface with hydrate formation and dissociation phenomena under equilibrium and non-equilibrium conditions at Basin and production time scales, respectively, along with supporting simulation results. I also discuss the impacts of Stokes/local Brinkman flow on the impermeable/permeable obstruction formation patterns such as hydrate/biofilm in evolving porous media. For simulations I use the Godunov-type finite volume method for the transport model with implicit-explicit time stepping method and the MAC (Marker and Cell) method on the staggered grid for the flow models.
