Experimental study and zone modelling of smoke movement in a model atrium
Bibliographic record
Abstract
A series of atrium model tests were conducted to investigate the effectiveness of the smoke exhaust system in an atrium. The dimension of the test compartment were 9 m x 6 m x 5.5 m height. The heat release rate ranged from 15 kW to 600 kW. The measured exhaust rate ranged from 1.94 to 5.13 kg/s. In this study, the experimental interface height between the smoke and cold layer is defined as the position with the maximum temperature or concentration gradient. Three sets of data, including the reduced interface height, smoke layer temperature, and CO2 concentration, are presented in this paper. The effects of some parameters on smoke conditions are analyzed. A two-zone smoke movement model is used to predict the interface height, smoke layer temperature, and CO2 concentration. This model is briefly described in this paper with the focus on the fluid flow model. It is shown that the model prediction compares favorably with experimental results, especially with smoke layer temperature. In addition, the effect of two plume models developed by McCaffrey and Heskestad on the interface height is investigated.

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.
