Abstract
Abstract. During the course of expansion of steam in turbines, the vapour rst supercools and then nucleates to become a two-phase mixture. Formation of the liquid phase causes thermodynamic and aerodynamic losses in steam turbines. In this study, the treatment is a one-dimensional, non-equilibrium ow in a steady Laval nozzle. In this paper, the changes in the rate of nucleation, entropy, pressure and other parameters of the two-phase \now, subjected to spraying the liquid droplets close to the nozzle's throat, are investigated. By injecting the water droplets into a supersonic condensing \now, the thermodynamic loss is considerably decreased.

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
