Abstract
A three dimensional computational fluid dynamics (CFD) simulation of coupled outdoor wind flow and indoor air flow is presented to investigate the effective parameters on cross ventilation and flow patterns inside an isolated house. Different opening positions are used to investigate the effect position of opening on the flow patterns inside the building. The study employed the low Reynolds number (LRNM) with Steady Reynolds Averaged Navier -Stokes (RANS) RNG k-e modelling approaches in the simulation. The CFD simulation is validated based on detailed wind tunnel experiments. The study showed that the efficiency of natural ventilation can be increased by following the behaviour of flow stream inside the house and controlling the recirculation areas which are formed in different rooms.

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
