Abstract

fetched live from OpenAlex

The effect of a fluctuating Lorentz force on the AC magnetohydrodynamic micropump is studied. A two-dimensional transient developing laminar flow is modeled. The governing Navier-Stokes equations are solved numerically using the finite-difference method and the SIMPLE algorithm. The effect of the Hartmann number on the transient and steady-flow velocity is studied. It is found that controlling the electrical conductivity and magnetic-flux density will allow us to control the entrance region length. The effect of the Stanton number and phase angle is also included, and it is found that at high frequency, the pulsed volume is small, which yields a continuous flow instead of a pulsating flow, and the magnitude and direction of the flow can be controlled by the phase shift between the electrical and magnetic fields.PACS Nos.: 45.20.dh, 47.10.dh, 47.11.dc, 47.15.Cb

Full frame distilled prediction

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.
