Numerical Study on High-speed Heterogeneous Condensation Flow of Wet Steam
Bibliographic record
Abstract
Based on sphere-cap-shaped nucleation mechanism,a numerical model of two-phase heterogeneous condensation flow of wet steam was established,with which numerical simulations were conducted on the heterogeneous condensation flow in Laval nozzle,turbine cascade and turbine stage respectively.Results show that in comparison with spontaneous condensation,the impurity particles in heterogeneous condensation flow change the condensation process,reduce the intensity of condensation shock in the Laval nozzle,alter the pressure distribution in the turbine cascade,reduce the supercooling degree of steam,and lower the thermodynamic loss of non-equilibrium.In the turbine stage,the inlet and outlet angle of heterogeneous condensation flow around rotor and stator are close to those of superheated steam flow,and its pressure before rotor blade is higher than that of superheated steam,but its degree of reaction deviates from corresponding values in superheated steam flow.

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.
