Abstract
We numerically investigated the changes in the collection efficiency of a cyclone separator depending on the hopper shape, that is, the particle collection section. We performed LES (large-eddy simulation), using a two-way model that considers the interaction between solid particles and gas. We tested various hopper shapes, including cylindrical and conical shapes. While there were almost no changes in the flow and particle behavior inside the cyclone separator, the flow within the hopper differed, leading to a bias in the particle collection locations. In terms of the collection efficiency, the conical hopper was slightly inferior compared to the others. We will discuss the behavior and causes of particles that were not collected in the hopper and flowed out from the cyclone separator.

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
