Abstract: HYPOTHESIS Determining capillary pressures and permeation resistances of multiphase seepage in porous-type reservoirs is crucial. The dynamic contact angle (CA) is one of the critical parameters used to calculate capillary pressures and permeation resistances. Under… read more here.

Abstract: Shear viscosity of bubbly liquids is known to depend on both the gas volume fraction and the capillary number. Here, we study the impact of confinement on their behavior by investigating the viscosity of semi-dilute… read more here.
