Numerical Analysis of Mixing Performance of a Novel ‘Y-U’ Split and Recombine Micromixer
Bibliographic record
Abstract
This work presents a design of a new micromixer named 'Y-U' based on the split and recombine (SAR) principle.Five mixers are constructed varying a parameter, vertical cylindrical connector height H (Y-UH), starting from 0 mm to 0.8 mm.Numerical analysis is carried out at Reynolds numbers ranging from 1 to 50 using FLUENT 15 for the purpose of optimization.A well-known SAR mixer, namely 'H' is also studied in order to validate the numerical model.Proposed Y-U mixers offer better mixing performance than H mixer regardless of Reynolds numbers.The Y-U mixers show more than 90% efficiency at low Reynolds numbers ( ≤ 1) and efficiency is about 60% for Reynolds numbers from 10 to 50.Mixing efficiency depends on the vertical cylindrical connector height (H); efficiency and pressure drop increases with the increase of vertical cylindrical height.Y-U0.8 mm (H = 0.8 mm) shows better maximum efficiency compare to all examined mixers.In addition, the mixing cost is independent of vertical cylindrical height.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
