Abstract

fetched live from OpenAlex

The presence of microfeatures/nanofeatures with sharp asperities on the emitter electrodes of ion drag electrohydrodynamic (EHD) micropumps is likely to enhance the local electric field and charge injection significantly, and thus the pressure generation and flow rates. The objective of this paper is to investigate the performance of EHD micropumps with single-walled carbon nanotubes (SWCNT) on the emitter electrodes. The micropumps had 100 pairs of planar electrodes where the width of the emitter and collector electrodes was 20 and 40 μm, respectively, with a cross-sectional domain of 100 μm × 5 mm. Two micropumps with interelectrode spacing of 120 and 40 μm were tested with a smooth emitter surface, and where SWCNT were electrophoretically deposited on the emitter electrodes using HFE7100 as the working fluid. The threshold voltage for charge injection lowered by a factor of 3 and 1.4 for the two pumps with SWCNT on the emitter electrodes compared with the smooth electrode case. The corresponding static pressure head increased by a factor 5, while the flow rate at no external back pressure increased by a factor 3 for the pump with interelectrode spacing of 120 μm. For the pump with interelectrode spacing of 40 μm, a maximum static pressure of 4.7 kPa was achieved at 900 V with SWCNT on the emitter electrode.

Not 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.
