Experimental and numerical study of a hydrocyclone with the modification of geometrical structure
Bibliographic record
Abstract
Abstract This paper proposes two kinds of structure‐modified hydrocyclone that exhibit better performance than the traditional ones. In type‐1, in which the outer edge of the vortex finder is hexagonal, the separation efficiency increases by 18.1 % compared to the conventional hydrocyclone, while type‐3, with a hexagonal conical section, can save 49.7 % of energy. To determine the reasons for the improvement in performance, numerical simulations are conducted to observe the flow field inside the hydrocyclones. Tangential, radial, and axial velocities are all studied in this research according to the simulation results. The radial velocity has a close relationship with separation efficiency. Based on the analysis, the separation mechanisms of different types of hydrocyclones are proposed. Furthermore, the air core, which is captured by a CCD camera, as a factor correlative to the flow pattern is also supportive of the improvement. The smoke area, which has many small air bubbles around the vortex finder, is defined in this work. The existence of the smoke area has a negative influence on energy transfer and separation efficiency.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
