Abstract
A type of supersonic separation structure is designed according to natural gas field condition and gas well drilling technology parameters. Based on the new device,a reasonable three-dimensional CFD model is established,and the realizable k-e turbulence model is selected to simulate the internal flow field of the supersonic separator. The separation parameters such as pressure,temperature,Mach number,and turbulence kinetic energy along the axis inside the supersonic separator are investigated,the flow characteristics along the radial direction in different sections are also discussed. The simulation results show that when the pressure loss ratio is 47. 5%,the shock wave will occur in divergent of the Laval nozzle( about 98 mm from the entrance of the supersonic separator). Due to the expansion effect of the Laval nozzle,the lowest temperature will achieve 190. 52 K. The calculation result agrees well with the previous experimental result. The new separator structure can also produce strong swirling intensity.Besides the calculation method gives a good guidance for the optimal design of the supersonic separator dimensions.

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 it
