Development of a multi-scale projection method with immersed boundaries for chemically reactive flows and its application to examine flame stabilization and blow-off mechanisms
… refinement (SAMR) framework and a semi-implicit operator-split projection algorithm. The immersed boundary approach captures the flame-wall interactions. The SAMR framework and the operator-split algorithm resolve several decades of length and time efficiently. A novel "buffer zone" methodology …

Parallel Processing of Reactive Transport Models Using OpenMP
… approaches that require a supercomputer. An operator-split strategy creates an environment for easy parallelization by decoupling the transport and reactions of species. The transport, when decoupled from the reactions, is dependent on surrounding nodes and not on species. Therefore, each …

The numerical study of 3-dimensional laminar hypersonic blunt-fin interactions
… Navier-Stokes equations. The numerical scheme is operator split, allowing independent numerical schemes to be used on each of the individual contributions to the Navier-Stokes, which can be combined later to advance the entire solution in time. The inviscid part uses a first order Godunov method …

Flow through porous media : from mixing of fluids to triggering of earthquakes
… using the unconditionally stable fixed-stress operator split for the sequential solution of two-way coupling between flow and geomechanics. We validate our modeling approach using test cases that illustrate the onset and evolution of earthquakes from fluid injection and production.

Modeling contaminant transport and fate and subsequent impacts on ecosystems
… concentration layer approximation and the operator split technique were used to solve the microscopic diffusion equation coupled with macroscopic advection and dispersion. The resulting model was employed for simulating Sr90 mobility at the U.S. Department of Energy (DOE) Hanford Site. The …

Simulation of hydrodynamics of the jet impingement using Arbitrary Lagrangian Eulerian formulation
… to implement the ALE formulation, namely the operator split approach and the fully coupled approach. This thesis presents a fully coupled ALE formulation for the simulation of flow field. ALE form of Navier-Stokes equations are derived from the basic principles of continuum mechanics and …
