The flow system may be changed from oil-wet to water-wet due to nanoparticles (which are also water-wet) deposition on surface of the pores. So, the model is extended to include the negative capillary pressure and mixed-wet relative permeability correlations to fit with the mixed-wet system. Moreover, buoyancy and capillary forces as well as Brownian diffusion and mechanical dispersion are considered in the mathematical model. An example of countercurrent imbibition in a core of small scale is considered. A dimensional analysis of the governing equations is introduced to examine contributions of each term of the model. Several important dimensionless numbers appear in the dimensionless equations, such as Darcy number Da, capillary number Ca, and Bond number Bo. Throughout this investigation, we monitor the changing of the fluids and solid properties due to addition of the nanoparticles using numerical experiments. dc.description.sponsorship This work was supported by the KAUST-UTAustin AEA project entitled "Simulation of Subsurface Geochemical Transport and Carbon Sequestration". dc.publisher Elsevier BV dc.subject Countercurrent imbibition dc.subject Dimensional analysis dc.subject Nanoparticles dc.subject Porous media dc.subject Two-phase flow dc.title Numerical and dimensional analysis of nanoparticles transport with two-phase flow in porous media dc.type Article dc.contributor.department Computational Transport Phenomena Lab dc.contributor.department Earth Science and Engineering Program dc.contributor.department Environmental Science and Engineering Program dc.contributor.department Physical Science and Engineering (PSE) Division dc.identifier.journal Journal of Petroleum Science and Engineering kaust.person El-Amin, Mohamed kaust.person Sun, Shuyu kaust.person Salama, Amgad
