Abstract

fetched live from OpenAlex

A numerical simulation of the flow inside a diffusing S-duct inlet is conducted. The primary discussion herein focuses on flow analysis and development of secondary flow in the S-duct diffuser inlet. Full three-dimensional Navier-Stokes equations are solved and SST turbulence model is employed. Numerical results, including surface static pressure, total pressure recovery at exit, are compared with experiment. And fairly good agreement is apparent. Total performance, such as average total pressure recovery and distortion, is agreed well with the experiment. Shock waves in outer flow, pressure recovery and distortion at the exit are also discussed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
