Abstract:
For many reservoir simulation problems, critical flow gradients occupy only a small
percentage of the flow domain, and the ability to perform local mesh refinement
is highly desirable. Moving away from conventional grid systems raises many issues
in terms of flow equation discretization. Hyperbolic and elliptic
adaptive-grid-interface flux approximations are presented and discretization issues
are discussed. Aquifer remediation simulations involving transport of steep
saturation gradients demonstrate that benefits of high resolution and reduced
computational cost are achievable when coupling adaptive local grid refinement
with higher-order schemes in three dimensions.
