Abstract
Abstract This study reports on the development of a complete solution methodology for the simulation of a hydrocyclone. A commercial software package, Ansys 12 Fluid Dynamics, is used to solve the governing conservation equations. Turbulence is modelled using the large eddy simulation, and the discrete particle model was used to predict the particle separation. Two hydrocyclones of differing geometries are explored, and the results compared with experimental values. It is shown that there are two key factors for obtaining a reliable result. The first is the domain discretisation, and the second is the generation of a consistent initial value, including the establishment of a stable air core. Using the methodology developed, superior agreement was obtained for predicted and experimental values of pressure, velocity distribution, air core profile and separation efficiency. © 2012 Canadian Society for Chemical Engineering

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
