| dc.description.abstract | The fluid thermodynamic properties under confinement deviate from those in the bulk phase. This PhD research quantifies these deviations by developing an Equation of State (EoS) based on the Statistical Associating Fluid Theory (SAFT). First-principle molecular dynamics (MD) simulations are then employed to determine the confinement parameters. Additionally, MD simulations are used to investigate the molecular aspects of Enhancing Oil Recovery (EoR) through Low Saline Water (LSW) injection, revealing that the expansion of the Electrical Double Layer is a primary factor in oil displacement by LSW. The methodology and outcomes presented here have broad applicability across various fields, including catalysis, enhanced oil recovery, CO2 storage, and contaminant transport. | en_US |
