Phase split of <scp>gas–non‐Newtonian</scp> fluid two‐phase flow in a ψ‐shaped branching microchannel
Bibliographic record
Abstract
Abstract An experiment of phase split was conducted in a horizontal ψ‐shaped branching microchannel to study the phase distribution and pressure drop at the bifurcation. The pressure drop at the test section and the flow rates of the gas and liquid phases through the three branches were measured. The pressure drop gradients at the inlet and branches were predicted by the correlation based on the separated flow model. The critical condition for the split of the two‐phase flow was determined. The results showed that the gas phase separated from the side arm was more than the liquid phase. A uniform distribution could be achieved for the churn flow in water. Pressure drop occurred at the bifurcation of the side arm under the effect of the vortex in the liquid slug near the bubble nose; the pressure drop was much greater than that at the bifurcation of the run.

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.
