Interfacial tension is the force between two dissimilar phases that can be gas-liquid, gas-solid, liquid-liquid, or liquid-solid interface. In the case of the gas-liquid interface and the gas-solid interface, terms of surface tension and surface free energy are used, respectively.
Modeling interfacial tension in hydrogen-water/brine systems for ...
2025年1月27日 · This work aims to develop exact predictive models to estimate IFT values expressed in mN/m. The models find the complex interactions between IFT and input variables using many advanced regression techniques. The regression methods used are XGB, LGBM, CatBoost, Random Forest, Gradient Boost, and Extra Trees.
Interfacial tension - MaterialsXpertise
The common units for interfacial tension (IFT) are mN/m. Excess energy exists at any type of interface. In case the surface investigated is the interface of two immiscible liquids, the measurement is normally referred to as interfacial tension (IFT).
Interfacial Tension (IFT) in Transformer Oil: Origins and Impact
2024年1月26日 · Interfacial Tension (IFT) measures the amounts of dissolved polar contaminants and oxidation by-products in electrical insulating fluids like mineral oil. A high value, usually for new insulating oil indicates the absence of undesirable polar contaminants.
IFT - Reservoir Engineering
IFT (Interfacial Tension) is the force acting at the boundary between two immiscible liquids, like oil and water. It dictates the tendency of one fluid to spread or contract at the interface. Higher IFT indicates a stronger attraction between molecules of the same fluid, making it …
Investigation of ionic liquid adsorption and interfacial tension ...
2024年5月10日 · The results revealed the significant effect of NaCl, KCl, CaCl 2, MgCl 2, CaSO 4, MgSO 4, and Na 2 SO 4 and pH values of 3.5–11 on the interfacial tension (IFT) reduction using three types of...
Modeling of interfacial tension in binary mixtures of CH4, CO2, …
2020年12月15日 · Interfacial tension (IFT) plays a key role in enhanced oil recovery (EOR) processes that involve the injection of light hydrocarbon and non-hydrocarbon gases into oil reservoirs.
Toward mechanistic understanding of heavy crude oil/brine …
2014年8月15日 · Injecting low salinity brines is regarded as an enhanced oil recovery (EOR) process through IFT reduction. However, the exact mechanism behind this process is an unsettled and complex issue that has not been well understood yet, especially for …
Detailed Assessment of Compositional and Interfacial Tension
2019年11月19日 · Mechanism 1 (M CE) is the conventional oil stripping/compositional effect, and Mechanism 2 (M IFT) is the near-miscible IFT effect on oil relative permeability through enhanced layer flow. We have studied how these M CE and M IFT mechanisms operate in a heterogeneous permeability field.
Measured and calculated IFT (in mN/m) for a concentration of …
The interfacial tension (IFT) around the critical micelle concentration was measured against a series of n-hydrocarbon to detect the minimum alkane carbon number (ACN) (Πmin) for each of...
