Numerical simulations of gas–liquid two‐phase flow in a recycling cyclone with different structural features
Bibliographic record
Abstract
Abstract Numerical simulations were employed to investigate the gas–liquid two‐phase flow within a recycling cyclone and the impact of key structural parameters on its separation performance. Using a coupled Reynolds stress model (RSM) for the gas phase and a discrete phase model (DPM) with a discrete random walk (DRW) for liquid droplets, this study analyzed the effects of the recycle line, gap width, baffle plate size, and entrance geometry. Results show that the recycle line significantly enhances separation efficiency, especially at lower inlet velocities. Optimal gap width and baffle plate size are crucial for balancing separation efficiency and operational reliability. While rectangular entrances offer slightly higher separation efficiency than circular ones, they also increase pressure drop. These findings offer valuable guidance for optimizing recycling cyclone design to improve particle separation in industrial settings.

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.
