Abstract
This study presents carbon dioxide separation from an air-CO2 mixture utilizing a vortex tube energy device at 4 and 5-barg pressures.Since the vortex tube reduces the temperature of the gas mixture at the cold gas exit, the vertically standing vortex tube with a bottom-side cold gas exit exhausts the CO2-rich gas mixture.As the inlet pressure is increased from 4 barg to 5 barg, the nozzle exit temperature of the CO2-air mixture is lowered at the cold gas exit temperature and raised at the hot gas exit temperature.The colder gas increases the separation percentage of CO2 from the air-CO2 mixture.Results show that the percent CO2 separation at 20% cold mass fraction is increased from 15.5% to 17.5% with a pressure increase of 4 to 5 barg.

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
