Pore‐scale modelling of immiscible displacement of <scp> ScCO <sub>2</sub> </scp> ‐brine in a homogeneous porous network using direct numerical method
Bibliographic record
Abstract
Abstract In this work, the pore‐scale dynamics of immiscible displacement of ScCO 2 –brine in a homogeneous pore network is studied using the volume of fluid method. The simulation results are verified with the theoretical equation and literature experimental data. First, the pore‐space filling is performed in a unit pore cell having an equal and unequal pore throat for both drainage and spontaneous imbibition. It is observed that the pore‐space filling sequence for drainage follows the rules described by the Young‐Laplace equation whereas the filling sequence did not follow the rule for spontaneous imbibition. Secondly, the simulation is performed for a homogeneous pore network. It is found that the transverse average volume fraction of ScCO 2 from the simulation matches with the experimental data for intermediate and higher capillary numbers. Further, the present simulation is extended to study the flow regime identification and viscosity ratio and contact angle effects on ScCO 2 volume fraction profile.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
