The Ganglion Network Model: Evolving Trapped Phases in Porous Media
Yashar Mehmani
Partially miscible ganglia trapped within porous media, spanning one or multiple pores and evolving through diffusive mass transfer, are common in subsurface (e.g., CO and H$_2…
Modeling Ostwald Ripening Dynamics in Porous Microstructures
Md Zahidul Islam Laku, Mohammad Salehpour, Tian Lan +2
Partially miscible ganglia trapped in a porous medium evolve through Ostwald ripening, driven by differences in interfacial curvature. In practice, ganglia can span multiple pores…
Kinetic Theory of Multicomponent Ostwald Ripening in Porous Media
Nicolas Bueno, Luis F. Ayala, Yashar Mehmani
Partially miscible bubble populations trapped in porous media are ubiquitous in subsurface applications such as underground hydrogen storage (UHS), where cyclic injections fragment…
Preconditioning and Reduced-Order Modeling of Navier-Stokes Equations in Complex Porous Microstructures
Kangan Li, Yashar Mehmani
We aim to solve the incompressible Navier-Stokes equations within the complex microstructure of a porous material. Discretizing the equations on a fine grid using a staggered (e.g.…
High-order Multiscale Preconditioner for Elasticity of Arbitrary Structures
Sabit Mahmood Khan, Yashar Mehmani
We present a two-level preconditioner for solving linear systems arising from the discretization of the elliptic, linear-elastic deformation equation, in displacement unknowns, ove…
Ostwald Ripening in Underground Gas Storage
Mohammad Salehpour, Tian Lan, Nicolas Bueno +3
Underground gas storage is central to both climate mitigation and energy transition strategies, supporting both long-term carbon sequestration and seasonal hydrogen storage. A key…
Wrinkle-Free Interface Compression for Two-Fluid Flows
Yashar Mehmani
Pure advection of a conservative scalar is relevant to several applications including two-phase flow. Successful numerical schemes must capture the sharp interface between the phas…
