A DNS study of droplet spreading and penetration on a porous medium
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)We have investigated the dynamics of droplet spreading and liquid penetration at the surface of a porous medium at zero-gravity condition. A coupled IBM-VOF finite volume code has been used to perform pore-scale level fully ... -
A numerical approach to model aggregate restructuring in shear flow using DEM in Lattice‐Boltzmann simulations
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Aggregate shape and structure significantly impact rheological properties of fluids in many fields such as extractive metallurgy, oil field drilling and mineral processing. The morphology of the aggregates determines the ... -
Direct numerical simulation of proppant transport in a narrow channel for hydraulic fracturing application
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)An efficient and accurate model for the direct numerical simulations (DNS) of liquid-solid flows is presented in this work. In this numerical model, fluid-solid coupling is achieved by implementing the no-slip boundary ... -
Immersed boundary method for the compressible Navier–Stokes equations using high order summation‐by‐parts difference operators
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)A ghost-point immersed boundary method is devised for the compressible Navier–Stokes equations by employing high order summation-by-parts (SBP) difference operators. The immersed boundaries are treated as sharp interfaces ... -
Multiphase Direct Numerical Simulations (DNS) of Oil-Water Flows Through Homogeneous Porous Rocks
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Water flooding is commonly used to recover oil from porous rocks using pressurized water. Present study focuses on fully resolved pore-scale level multiphase Direct Numerical Simulations (DNS) of oil-water flows through ...
