Simulation and Validation of Airflow Distribution Patterns in Bins Filled with Canola
Bibliographic record
Abstract
A non-linear model that can explain three dimensional airflow pressure patterns in bins filled with canola was developed using the finite element method. Resistance to airflow through the porous matrix (canola) was described using a modified form of Darcy’s equation. The airflow model was validated against experimental data obtained from studies conducted in a flat bottom bin of 4.6 m diameter containing‘Tobin’ canola, aerated using a fully perforated floor. The average relative error between the experimental and predicted values for the entire bin geometry was 1.8 per cent. Relative error values decreased with increasing grain bed height and bin diameter. The airflow pressure patterns resulting from eight other duct configurations were simulated. The model can be used to predict the airflow distribution in various grain beds and has the capability to handle variations in product type, moisture content, foreign material content, direction of airflow and aeration duct designs.

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.
