Квазиодномерный расчет течения газа в турбинных соплах с косым срезом
Bibliographic record
Abstract
In article the gas flow in axial turbines with a slanting cut is considered. The curvilinear channel is straightened for performance of calculations. It is supposed that parameters of gas remain constants in cross sections. It also makes an essence of quasi-one-dimensional approach. Three views of nozzle canals are considered: Laval´s nozzle with a slanting cut from critical section, Laval´s direct nozzle and a confluence nozzle. Calculations were carried out for the concrete snuffled, other authors brought in publications. As a result of calculations it is received that the set counter-pressures correspond to supersonic modes of reexpansion for a direct nozzle. Output numbers of the Mach taking into account the set counter-pressure were calculated. As calculations of parameters of gas in studied channels were executed in two-dimensional approach. The analysis of the received results showed that quasi-one-dimensional current calculation in confluence nozzle taking into account the neighboring canals, most is true.

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.
