Structure design and numerical simulation of novel supersonic swirling separator
Bibliographic record
Abstract
The static guide vanes were installed at the entrance of Laval nozzle in the novel supersonic swirling separator.The natural gas was swirled when going through the vanes,and then expanded in the Laval nozzle.In this new separator,the shock waves could be easily restricted in the diffuser.The energy loss and the impact of re-evaporation could be reduced,which would improve the separation and pressure recovery performance.The flow law in the separator was obtained by numerical simulation.The results show that shock waves move to Laval nozzle from the diffuser with the increase of the relative pressure ratio,which is the ratio of the static pressure of the separator outlet to the inlet.When the relative pressure ratio is from 40% to 73%,the novel supersonic swirling separator can work.At the nozzle exit,the Mach number is 2.0,resulting in lower temperature(-98.82 ℃)and pressure(82.945 kPa).The maximal swirling acceleration is 243 558g(g is the acceleration of gravity).The gas-liquid separation of supersonic gas can be realized well.

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.
