Effect of Contact Angle on Capillary Pressure and Liquid Recovery from Angular Pore Channels
Afshin Davarpanah, Simon Cox
We predict the volume of liquid recovered from different-shaped prismatic channels following gas displacement. This recovery factor depends strongly on the contact angle at which t…
Prediction of the capillary pressure of fluid surrounding a cylinder representing an idealized rock structure in porous media
Afshin Davarpanah, Simon Cox
Liquids in oil-bearing porous media assume complex shapes that depend on the reservoir characteristics and the wetting properties of the liquid. The wide variation in the geometry…
Interface shapes in microfluidic porous media: conditions allowing steady, simultaneous two-phase flow
S. J. Cox, A. Davarpanah, W. R. Rossen
Microfluidic devices offer unique opportunities to directly observe multiphase flow in porous media. However, as a direct representation of flow in geological pore networks, conven…
An analytic velocity profile for pressure-driven flow of a Bingham fluid in a curved channel
Tirion G. Roberts, Simon J. Cox
We derive an expression for the velocity profile of a pressure-driven yield-stress fluid flow-ing around a two-dimensional concentric annulus. This result allows the prediction of…
Semi-analytic velocity profile for a Bingham fluid in a curved channel
Tirion G. Roberts, Simon J. Cox
We derive an expression for the velocity profile of a pressure-driven yield-stress Bingham fluid flowing around a 2D concentric annulus. The formula requires the numerical solution…
Structure-dependent mobility of a dry aqueous foam flowing along two parallel channels
Sian A. Jones, Benjamin Dollet, Yves Méheust +2
The velocity of a two-dimensional aqueous foam has been measured as it flows through two parallel channels, at a constant overall volumetric flow rate. The flux distribution betwee…
