Abstract

fetched live from OpenAlex

The electrohydrodynamically enhanced natural convection of dielectric liquids in a horizontally cylindrical annulus was numerically investigated under DC and pulsed applied electric field conditions over the range of Rayleigh number from 10/sup 4/ to 2*10/sup 4/, the Prandtl number from 5 to 7, and the electric Rayleigh number from 0 to 2*10/sup 3/ for the inner-to-outer radius ratio of 2. Simulation results show that the applied, radial, DC electric field always enhances the heat transfer by natural convection process. The velocity and heat transfer enhancement are from a factor of 2 to 20 and from 10% to 30%, respectively, for EI varying from 5*10/sup 2/ to 2*10/sup 3/.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Teacher imitation

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.
