Abstract

Fully implicit, fully coupled techniques are developed for simulatingmultiphase flow with nonequilibrium mass transfer between phases, with application to groundwater contaminant flow and transport. Numericalissues which are addressed include: use of MUSCL or Van Leer flux limiters to reduce numerical dispersion, use of full or approximate Jacobian for flux limiter methods, and variable substitution for increased Newton iteration efficiency. A comparison of the performance of equilibrium and nonequilibrium models is also presented. (C) 1998 Elsevier Science Limited. All rights reserved.
