Abstract
Curved microchannels take advantage of inertial and Dean drag forces to achieve size-based separation of particles and cells. Despite the reported numerical and experimental correlations for Dean velocity (VDe) of Newtonian fluids, comprehensive studies and correlations are still required for the flow of viscoelastic fluids in curved microchannels. In this paper, the effects of curved channel height, radius of curvature, and kinematic viscosity were investigated to derive an empirical correlation for VDe of viscoelastic water. The developed knowledge of viscoelastic Dean flow velocity will be vital in design of elasto-inertial microfluidic devices for determination of lateral displacement of fluids in fluid exchange and Dean drag force in particle focusing and separation applications.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
