The Numerical Simulation of a Passive Interdigital Micromixer With Uneven Lamellar Width
Bibliographic record
Abstract
In this paper, a passive micromixer with interdigital structure is proposed and investigated using numerical simulations. The micromixer contains three layers to achieve the interdigital flow structure. The height of mixing channels is fixed as 0.2 mm. The total width of inlets is 0.9 mm. The mixing regime is rectangular in shape. The Reynolds number, measured at the entrance of straight channel, ranges from 5 to 60. Grid independence is performed to minimize the influence of numerical diffusion on simulation results. The grid size is selected as 6 μm, which can be considered as optimal. The interdigital micromixers with straight downstream channels are designed and simulated. In order to achieve better mixing near the inner walls, uneven lamellae width of each species is applied to create a larger concentration gradient near the inner walls. The results show that the micromixer with uneven lamellar width is able to enhance the mixing near the inner walls. A new passive micromixer with the uneven interdigital inlets is also designed to improve the mixing efficiency at high Re. The simulation results show that this new micromixer has a mixing efficiency larger than 80%, and a maximum pressure drop of 2.7 KPa.

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.
