Description:

With technological advances in computational facilities during the past two decades, the use of pore-scale models, especially for analysis of multi-phase flow, has increased dramatically, with applications in hydrogeology, reservoir engineering and various industrial processes. The computational techniques for pore-scale modeling include pore-network modeling, Lattice-Boltzmann, level-set methods, traditional Navier-Stokes solvers, and other solvers, and they each have their specific advantages and disadvantages. Pore-scale models provide new physical insights into processes, and provide quantitative information for higher-scale models. On the other hand, multiphase flow phenomena at various scales continue to present modeling challenges in new applications and in multi-component systems where mass transfer, phase transitions, and solubility constraints are important. This session will bring together scientists who a) employ and develop computational pore-scale models for diverse application of porous media, b) investigate challenges, advances, and perspectives in computational aspects of multiphase and multi-component models between various scales.
