Flux corrected transport applied to hydrodynamics for heavy ion collisions
This thesis presents FCTHydro, a ROOT package, and its application to hydrodynamic simulations through the packages RelHydro and Nonideal xy. These packages aim to provide the broader heavy ion collision community with access to hydrodynamic simulation software which is now accessible from within …

Design and application of flux corrected transport for reactive solute transport modeling
Understanding reactive solute transport, which couples flow , transport, and chemical/ biological reaction in porous media, is important in areas such as aquifer remediation, groundwater contamination and geochemical reaction modeling. Due to the large time scales involved, lack of accessibility to …
