Stability of multiphase liquid media

Sound Speed and Attenuation in Multiphase Media

One research goal developed from conducted shallow water (SW) acoustic transmission experiments in sandy-silty areas [1] revealed a nonlinear power law frequency-dependent attenuation at lower frequencies ( ≤ 1 kHz ) consistent with results reviewed in [2-4] and the observations by the ONR-HEP program. The Biot Theory [5] predicts that the sandysediment frequency-dependent attenuation should be...

Numerical analyses of effective dielectric constant of multiphase microporous media

This paper provides a full numerical tool set for modeling and predicting an effective apparent dielectric constant of multiphase microporous media, which includes a multiparameter random generation-growth algorithm for generating microstructures of multiphase porous media and a lattice Boltzmann solver for the electric potential transport equations through porous structures. After being valida...

Direct Numerical Simulations of Gas-Liquid Multiphase Flows

Numerical Modeling of Multiphase Flow in Porous Media

The simultaneous flow of immiscible fluids in porous media occurs in a wide variety of applications. The equations governing these flows are inherently nonlinear, and the geometries and material properties characterizing many problems in petroleum and groundwater engineering can be quite irregular. As a result, numerical simulation often offers the only viable approach to the mathematical model...
