Effect of Fan Hub Configuration on the Cooling Airflow through Electric Motors in Engine Cooling Fan Systems
Bibliographic record
Abstract
<div class="htmlview paragraph">Typical automotive engine-cooling fan assemblies include an electric motor having a driveshaft coupled to a fan. The typical fan includes a hub, which extends from the driveshaft to the root of the fan blades. Radial ribs are incorporated within the hub to stiffen the fan structure. The fan hub including the ribs pulls cooling air through the motor, thus preventing it from overheating.</div> <div class="htmlview paragraph">Experimental tests and computational fluid dynamics (CFD) simulations have been carried out to investigate the effects of fan hub configurations on cooling airflow through the electric motor in automotive cooling fan systems. It has been found that radial ribs on the fan hub have significant effects on drawing cooling air through the motor. The comparison of the simulation results with the pressures measured in laboratory experiments show good agreement.</div>

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.
