Abstract
Data centers require vast amounts of energy for keeping the servers cool at optimal operating temperatures. Recent research has focused on improving the cooling efficiency, and thereby lowering the energy consumption, through different rack arrangements and modifying the air-flow patterns. Thus far, this has been done using computational fluid dynamics (CFD) models as access to a real data centers is often restricted. The next step in this research is to build a physical model for testing purposes. The viability of building a scaled model of an actual data center is investigated using the scale modeling theory for airflow experiments. A full-scale prototype and a half-scale model are created using CFD software and simulated to see if similarity can be achieved in the scaled model for the temperature distribution as well as the airflow velocities. Our results show that the thermal similarity can be achieved within 5% error margin while the airflow similarity cannot be achieved with reasonable accuracy.

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
