Testing a coupled hydro-thermo-chemo-geomechanical model for gas hydrate bearing sediments using triaxial compression lab experiments
Shubhangi Gupta, Christian Deusner, Matthias Haeckel +2
Natural gas hydrates are considered a potential resource for gas production on industrial scales. Gas hydrates contribute to the strength and stiffness of the hydrate-bearing sedim…
Solution Techniques for the Stokes System: A priori and a posteriori modifications, resilient algorithms
Markus Huber, Lorenz John, Petra Pustejovska +3
This article proposes modifications to standard low order finite element approximations of the Stokes system with the goal of improving both the approximation quality and the paral…
A quantitative performance analysis for Stokes solvers at the extreme scale
Björn Gmeiner, Markus Huber, Lorenz John +2
This article presents a systematic quantitative performance analysis for large finite element computations on extreme scale computing systems. Three parallel iterative solvers for…
Multi-rate time stepping schemes for hydro-geomechanical model for subsurface methane hydrate reservoirs
Shubhangi Gupta, Barbara I. Wohlmuth, Rainer Helmig
We present an extrapolation-based semi-implicit multirate time stepping (MRT) scheme and a compound-fast MRT scheme for a naturally partitioned, multi-time-scale hydro-geomechanica…
Pore-scale lattice Boltzmann simulation of laminar and turbulent flow through a sphere pack
Ehsan Fattahia, Christian Waluga, Barbara Wohlmuth +3
The lattice Boltzmann method can be used to simulate flow through porous media with full geometrical resolution. With such a direct numerical simulation, it becomes possible to stu…
Non-Isothermal, Multi-phase, Multi-component Flows through Deformable Methane Hydrate Reservoirs
Shubhangi Gupta, Rainer Helmig, Barbara Wohlmuth
We present a hydro-geomechanical model for subsurface methane hydrate systems. Our model considers kinetic hydrate phase change and non-isothermal, multi-phase, multi-component flo…
