Research on atomized droplet size in composite quench chamber
Bibliographic record
Abstract
A cold state device of a composite spray quench chamber was established. In order to obtain the distribution of atomized droplet sizes at radial and axial positions along the flow field, different combinations of multi‐spray nozzles were selected. The atomized droplet size along the axial position was measured using a Malvern Spraytec under different conditions. The results showed that Sauter Mean Diameter (SMD) D32 near the nozzles was mainly influenced by liquid flow rate. However, D32 further away from the nozzles was affected by both liquid and gas flow rate. Along the axial direction, with increasing of the relative height (h/H), D32 decreased. D32 around the gas outlet was mainly affected by the gas flow rate, growing from 80 to 160 µm as the gas flow rate increased from 0.29 to 0.49 m · s−1, which was similar to the calculated data. The research can optimize and improve the internal structure of a spray quench chamber, providing guidance to industrial applications.

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.
