Abstract
Velocities and temperatures in a large room heated to nearly 20 °C by an electric resistance and ventilated by a cool (16 °C) horizontal jet were measured along eight different vertical lines. These measurements are used in conjunction with corresponding numerical predictions by the RNG k-ε model to describe the hydrodynamic and thermal fields in the room. The interaction between the horizontal ventilation jet (which remains attached to the ceiling since both its inlet and outlet are in the ceiling) and the natural convection movement (which is upward above the electric heater and downward along the cold wall and windows) creates a complex 3D flow field. The CFD model is also used to study the effect of the air outlet position on the flow field and the net energy outflow due to ventilation. This last quantity represents 48% to 63% of the power delivered by the electric resistance.

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
