Nonisothermal global-pressure exactness in fractured multiphase flow with aperture feedback
Christian Tantardini, Fernando Alonso-Marroquin
Global-pressure formulations recast multiphase Darcy flow in terms of a single pressure driving the total flux. Their exact equivalence to phase-pressure formulations holds only wh…
A Nonhomogeneous Porous-Medium Equation for Field Scale CO Plume Spreading
Fernando Alonso-Marroquin, Christian Tantardini
We derive a nonlinear diffusion model for field scale CO plume spreading from a Global Buckley--Leverett component balance. The reduced variable is the vertically averaged…
Representative-volume sizing in finite cylindrical computed tomography by low-wavenumber spectral convergence
Fernando Alonso-Marroquin, Abdullah Alqubalee, Christian Tantardini
Choosing a representative element volume (REV) from finite cylindrical Computed Tomography (CT) scans becomes ambiguous when a key field variable exhibits a slow axial trend, refle…
Global Buckley-Leverett theory for multicomponent flow in fractured media: Isothermal equation-of-state coupling and dynamic capillarity
Christian Tantardini, Fernando Alonso-Marroquin
We present an isothermal Global Buckley--Leverett framework for multicomponent, multiphase flow in porous and fractured media that retains the interpretability of classical Buckley…
Capillarity in Stationary Random Granular Media: Distribution-Aware Screening and Quantitative Supercell Sizing
Christian Tantardini, Fernando Alonso-Marroquin
We develop a quantitative framework to determine the minimal periodic supercell required for representative simulations of capillarity-screened Darcy flow in stationary random, pol…
