Abstract
A new micromixer named '(Y-U)H' is proposed based on the split and recombine (SAR) principle. Five different (Y-U)H mixers are constructed with varying vertical cylindrical connector height H. The optimization is carried out by changingthe height H from 0 mm to 0.8 mm at varying Reynolds numbers ranging from 1 to 100 using numerical simulation software Ansys 15.The numerical setup is validated by comparing the numerical data with the experimental results of a well-known SAR 'H' mixer.Proposed (Y-U)H mixers have superior mixing performance than the H mixer irrespective of Reynolds numbers.Furthermore, the (Y-U)H mixers show excellent efficiency ( > 90%) at low Reynolds numbers ( 1).However, efficiency declines with the incline of Reynolds numbers due to the absence of secondary flow, and efficiency is about 64% for Reynolds numbers ranging from 10 to 100.Mixing efficiency also depends on the vertical cylindrical connector height (H); both efficiency and pressure drop increase with the increase of vertical cylindrical height.The (Y-U)0.8 mm (H = 0.8 mm) mixer shows the highest maximum efficiency (74%) compared to all examined mixers.

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
