Variational inequality approach to enforce the non-negative constraint for advection-diffusion equations
J. Chang, K. B. Nakshatrala
Predictive simulations are crucial for the success of many subsurface applications, and it is highly desirable to obtain accurate non-negative solutions for transport equations in…

Modeling flow in porous media with double porosity/permeability: Mathematical model, properties, and analytical solutions
K. B. Nakshatrala, S. H. S. Joodat, R. Ballarini
Geo-materials such as vuggy carbonates are known to exhibit multiple spatial scales. A common manifestation of spatial scales is the presence of (at least) two different scales of…

A hybrid multi-time-step framework for pore-scale and continuum-scale modeling of solute transport in porous media
S. Karimi, K. B. Nakshatrala
In this paper, we propose a computational framework,which is based on a domain decomposition technique, to employ both finite element method (which is a popular continuum modeling…
