Abstract
The numerical simulation of three-dimensional viscous flow was carried out to investigate the effects of different diffuser stagger angle on flow field and performance of a high-speed centrifugal compressor.The numerical results indicated that the influence of different stagger angles on flow filed and performance of the centrifugal compressor is great.Too small stagger angle will cause flow channel blockage and Laval nozzle effect which greatly reduce the compressor efficiency.As the stagger angle which is in a appropriate range increases,the compressor's total pressure ratio and isentropic efficiency increased,but its surge margin is gradually reduced.In short,the stagger angle of vaned diffuser should be determined by efficiency,pressure ratio and surge margin.

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
