DOI: 10.1002/aic.15723

Abstract: Various computational fluid dynamics methods have been developed to study the hydrodynamics of gas-solid flows, however, none of those methods is suitable for all the problems encountered due to the inherent multiscale characteristics of gas-solid… read more here.

DOI: 10.1016/j.petrol.2019.02.009

Abstract: Abstract Geomechanical characteristics should be simulated accurately given their significant effects on the whole flow patterns in porous media. However, the coupled geomechanics and flow simulation imposes severe computational challenges to the computer resources. Therefore,… read more here.
