Space–time domain decomposition for two-phase flow between different rock types

Effective Model of Two-phase Flow in a Porous Medium Made of Different Rock Types

We consider the behavior of immiscible and incompressible two-phase ows in a porous medium made of several rock types. Each rock type, is deened by one porosity, one absolute rock permeability ten-sor, two relative permeability curves and one capillary pressure curve. Using two-scale convergence, we get an homogenized model which governs the global behavior of the ow. In this model, macroscopic...

Elastico-Viscous Flow between Two Rotating Discs of Different Transpiration for High Reynolds Numbers (RESEARCH NOTE)

The flow in an elastico-viscous fluid between two co-axial infinite rotating porous discs is considered for high cross flow Reynolds number. The discs are rotating with different angular velocity and the injection rate of the fluid at one disc is different from the suction rate of other disc. The effect of suction parameters on the velocity components have been investigated numerically and solv...

A method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow

Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...

Rock Stability under Different Fluid Flow Conditions

Phase transitions for rock-scissors-paper game on different networks.

Monte Carlo simulations and dynamical mean-field approximations are performed to study the phase transitions in the rock-scissors-paper game on different host networks. These graphs are originated from lattices by introducing quenched and annealed randomness simultaneously. In the resulting phase diagrams three different stationary states are identified for all structures. The comparison of res...
