Introduction As one mechanism of chemical flooding, a high molecular polymer is added to a water solution to increase water viscosity and reduce water-oil mobility ratio, thereby inhibiting the fingering of the displacing phase … WebThis paper addresses simulation of non-isothermal water-oil displacements in porous media at pore-scale. The simulation approach was done by coupling Cahn–Hilliard phase field and heat equations using COMSOL Multiphysics. Finite element method with interfacial adaptive mesh refinement was employed to solve the equation system.
Macroscopic Equations of Motion for Two Phase Flow in Porous Media
WebPore-scale simulation of CO2 front progression through a porous medium has been investigated by a free energy model based on phase-field lattice Boltzmann method. Visualization of the fluids distribution in the breakthrough time reveals a strong dependence of front pattern on viscous and capillary forces interaction. WebThe problem of viscous instabilities in porous media is one that continues to receive attention in a wide variety of fields due to the ubiquity of applications of ... bilities in analytical chemistry applications, notably in both laboratory scale and large scale chromatographic separations in which the property variations of chemical mixtures ... cincinnati group health associates mychart
Influence of Viscous and Capillary Forces on Immiscible Fluid ...
Web2.3. Porous Media. To study the effect of permeability on displacement efficiency, two sets of porous media are used; a layers etched glass pore network and a set of Berea … WebThe dominant mechanisms of surfactant for increasing oil production are wettability alteration of reservoir rock and interfacial tension (IFT) reduction of oil-water system resulting in higher sweep efficiency by diminishing the adverse capillary forces existing in the porous media and easier flow of the residual oil toward the producing wells. WebThis model is based on the volume averaging of the governing equations. Interstitial quantities are obtained through means of a pore-scale model. For flow through porous media, in the Darcy regime, the interstitial fluid–solid interaction component is written in terms of the interstitial wall shear stress. dhs leads
