Dynamic Capillary Effects in the Simulation of Flow and Transport in Porous Media: A New Linearisation Method
(Master thesis, 2014-12-25)In this thesis mathematical models with and without dynamic capillary effects are developed to model water flow and solute transport through a porous medium. The system of equations are discretised using the finite volume ... -
Establishing a homogeneous and stable sand pack to study parameters during spontaneous imbibition
(Master thesis, 2018-06-20)Spontaneous imbibition is an important process for oil production during water flooding in porous media and has been widely studied for decades to understand the physics of the process for different boundary conditions. ... -
An Experimental Study of Methane Hydrate Growth and Dissociation in Porous Media
(Master thesis, 2015-06-01)Natural gas hydrate (NGH) is a solid phase consisting of water and natural gas. NGH represents a justified vast global energy resource, and is widespread in on-shore artic and sub-seafloor environments. Due to the worlds ... -
Natural Convection in Layered Porous Media between Coaxial Cylinders
(Master thesis, 2015-05-31)In this thesis a mathematical model is developed to describe the onset of natural convection in a two-layer porous medium located between two coaxial cylinders, motivated by natural convection processes in geothermal ... -
Pore-scale investigation of methane hydrate phase transitions and growth rates in synthetic porous media
(Master thesis, 2018-06-20)A growing demand for energy and natural gas in particular, makes methane gas hydrates a potential target to supplement natural gas production from conventional resources. Several pilot projects have proven the feasibility ... -
A robust implicit scheme for two-phase flow in porous media
(Master thesis, 2015-11-26)In this thesis we present a new implicit scheme for the numerical simulation of two-phase flow in porous media. Linear finite elements are considered for the spatial discretization. The scheme is based on the iterative ...
