Abstract
This paper investigates underbody aero-thermal management of a hypothetical battery pack. Underbody diffusers are specifically designed to channel air for cooling a surface of the battery pack without significantly increasing aerodynamic drag. Numerical simulations are conducted to study the cooling and drag effects of the new diffusers on the battery pack. The numerical results show that the temperature of the battery pack upstream decreased whereas that at the downstream slightly increased compared to the no diffuser case, in addition to having a larger range of temperatures. There are smaller hot spots in comparison to the no diffuser case, which limit the number of cells in a battery that would be affected by the temperature increase, thus preventing damage. With further studies and improved diffuser design, the present work has the potential to offer better alternative locations for installing EV and HEV battery packs for improved air cooling.

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 it
