Abstract

 IN THIS STUDY, A COMPUTATIONAL FLUID DYNAMICS METHOD HAS BEEN DEVELOPED TO SIMULATE THE NANOFLUID FLOODING IN A 2D MICRO POROUS MEDIUM. A SERIES OF METAL-OXIDES NANOPARTICLES SUCH AS CUO, AL2O3 AND TIO2 AND SILICA IN THE DISTILLATED WATER AS THE BASE OF NANOFLUID WERE CONSIDERED. THE MICROMODEL GEOMETRY WAS GENERATED USING MATLAB AND ALSO THE COMMERCIAL GRID GENERATION TOOL, GAMBIT 2.3, TO CREATE THE DESIRABLE POROUS MEDIUM. THEN, GOVERNING EQUATIONS WERE SOLVED BASED ON FINITE VOLUME METHOD USING THE FLUENT 6.3 SOFTWARE TO INVESTIGATE THE DISPLACEMENT OF OIL AT THE PORE SCALE. THE SIMULATION RESULTS HAVE BEEN EVALUATED BY COMPARING WITH EXPERIMENTAL RESULTS IN TERM OF OIL RECOVERY FACTOR. IN ORDER TO BETTER UNDERSTAND EFFECTS OF NANOPARTICLES, RESULTS HAVE BEEN COMPARED WITH WATER FLOODING. IT HAS BEEN FOUND THAT NANOPARTICLES CAUSE ENHANCEMENT OF SWEEP EFFICIENCY DURING THE FLOODING AND DECREASE NUMBER OF FINGERS. IN ADDITION, NUMERICAL RESULTS SHOW THAT AT HIGHER PORE VOLUME INJECTED (PV˃0.4), EFFECTS OF NANOPARTICLES ARE MORE SIGNIFICANT.
