Colloid transport in a single fracture-matrix system: Gravity effects, influence of colloid size and density
Bagalkot, Nikhil Lakshmish; Kumar, G. Suresh (Journal article; Peer reviewed, 2018-10)A numerical model was developed to investigate the influence of gravitational force on the transport of colloids in a single horizontal fracture–matrix system. Along with major transport phenomena, prominence was given to ... -
Dynamic interfacial tension measurement method using axisymmetric drop shape analysis
Bagalkot, Nikhil Lakshmish; Hamouda, Aly Anis; Isdahl, Ole Morten Robertsen (Journal article; Peer reviewed, 2018-06)The current method describes a simple modification to the dynamic and equilibrium interfacial tension (IFT) measurement in a multiphase system (gas-liquid/liquid-liquid) by the Axisymmetric Drop Shape Analysis (ADSA) pendant ... -
Effect of Salts on Interfacial Tension and CO2 Mass Transfer in Carbonated Water Injection
Hamouda, Aly; Bagalkot, Nikhil Lakshmish (Journal article; Peer reviewed, 2019-02)Carbonated water injection (CWI) is a promising enhanced oil recovery (EOR) and CO2 sequestration method, which overcomes the problems associated with CO2 EOR. CO2 mass transfer and interfacial tension (IFT) are important ... -
Influence of Fracture Heterogeneity Using Linear Congruential Generator (LCG) on the Thermal Front Propagation in a Single Geothermal Fracture-Rock Matrix System
Bagalkot, Nikhil Lakshmish; Zare, Alireza; Kumar, G. Suresh (Journal article; Peer reviewed, 2018-04)An implicit finite difference numerical model has been developed to investigate the influence of fracture heterogeneity on the propagation of thermal front in a single horizontal fracture-matrix system. Instead of depending ... -
Interfacial tension and CO2 diffusion coefficients for a CO2 + water and n-decane system at pressures of 10 to 160 bar
Bagalkot, Nikhil Lakshmish; Hamouda, Aly Anis (Journal article; Peer reviewed, 2018-11)The objective of this study is to address the influence of different CO2 phases and degrees of CO2 saturation on the interfacial tension and the diffusion of CO2 into a hydrocarbon drop. Axisymmetric drop shape analysis ...
