CALCULATION OF AIRFLOW SPEED FROM A TURBINE WITH AN INTEGRATED LAVAL NOZZLE AT THE OUTLET FOR METAL COATING BY COLD SPRAYING METHOD
Bibliographic record
Abstract
The goal of this work was to test the practicability of using a device that provides airflow into the Laval nozzle channel to enable the application of metal coating by cold spraying. A turbine with an integrated Laval nozzle at the outlet was considered as a device to provide airflow into the Laval nozzle channel. The authors describe the equipment used in the calculations and the experimental study, the process of gasdynamic calculation of the output velocity of the airflow injected by the turbine impeller and the results of this calculation with precise indices. As a result, functional dependences of the indicators that provide the possibility of using the turbine as a source of airflow have been obtained, and a conclusion about the inexpediency of using a turbine with an integrated Laval nozzle at the outlet to provide the possibility of metal coating by cold spraying has been formed.

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.
