Numerical Simulation Study on the Descaling Mechanism of High-Pressure Swirling Jet
Bibliographic record
Abstract
To further explore the active mechanism of swirling jet， a numerical model of swirling jet descaling was built， and its effectiveness was verified by comparing with experimental results. Then， the difference in flow field characteristics between swirling jet and conventional straight jet was compared， and the mechanism of overflow and erosion in the process of swirling jet descaling was revealed. Finally， the influence of pump pressure， target distance and jet angle on the descaling performance was analyzed. The study results show that the special nozzle structure determines the three-dimensional velocity distribution characteristics of the swirling jet. The swirling jet has a similar impact crushing capacity and a larger impact area as the conventional straight jet. An increase in pump pressure can significantly improve the descaling performance of the swirling jet， the target distance has an optimal value for affecting the descaling performance， and moderately increasing the jet angle can further promote the descaling effect. The study results provide reference for the optimal application of swirling jet in descaling operations.

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.
