Abstract
In this paper the k e model and discrete radiation intension method have been used to simulate numerically the temperature and flow fields of the gas baking method to start up the aluminum electrolytic cell on the assumption that the absorption coefficient of radiation is not affected by turbulent character and the temperature of the gas in the cell is under 1 200 ℃.Because the source item of energy function is described by the discrete radiation intension method,the complex integral calculation about radiation is simplified in the numerical model.The functions can be solved by SIMPLER method.The investigation revealed that in initial baking stages,the temperature difference of the cell surface was about 197 ℃ at low heat load;with the rising of heat load,the temperature field became more even;at the end,the temperature difference was under 100 ℃ and the temperature distribution was substantially uniform on the surface.The simulation agrees well with the experimental results of industrial.The research conclusions provide the theoretical basis for the gas baking method of aluminum electrolytic cell.

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
