Abstract
A new annular supersonic nozzle was designed for natural gas dehydration based on the principle of conservation of angular momentum.Corresponding mathematical and physical models were established.The flow characteristics of natural gas in the annular supersonic nozzle were numerically simulated with the RNG k-eturbulence model.The results showed that natural gas expanded to supersonic velocity,resulting in a low temperature in the annular nozzles.The Mach number could reach 1.85 at a low temperature of-70 ℃ at the nozzle exit.The swirling motion was generated by the vanes located at the entrance of the nozzle,leading to a centrifugal field of about 640 000g.Water could be condensed and removed from natural gas under the combined effects of low temperature and strong centrifugal field.The strong swirling flow could be obtained in the annular nozzle as a result of the central body.When the swirling flow passed through the nozzle,the expansion characteristics of the nozzle was weakened,which was different from the common Laval nozzle.

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.
