Flow field simulation and structural optimization of the top fan drying room based on CFD
Bibliographic record
Abstract
In order to improve the wind-speed uniformity field distribution in the hot air drying room, the numerical simulation analysis of the internal three-dimensional wind speed field was carried out by using the hot air drying room of the top fan type as the model. The wind-speed uniformity field was used to quantify the evaluation index, and the optimal scheme was screened by data comparison analysis. Eight structural optimization schemes were proposed by using three design methods: curved right-angle structure, adjustment of saw spacing, and increase or decrease of the number of average wind plates. The wind speed field distribution between the original structure model and the Structure optimization scheme under different wind speeds was compared (3m/s, 5m/s, 7m/s) and analyzed. It was found that there was a positive correlation between the wind speed data between the air inlet and the sampling point. The test results show that when the inlet wind speed is 5m/s, the velocity non-uniformity coefficient of optimal scheme B2 is 82.34% lower than that of the original structure model, the difference of wind speed sampling points is reduced by 106.2%, and the average wind speed in the drying room is increased by 12.88%. After the structural optimization, the area of the low-speed turbulent region of the drying room is reduced, the wind speed difference in the drying area is reduced, and the wind-speed uniformity in the drying room is improved.

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.
