Abstract

fetched live from OpenAlex

Large eddy simulations are used to study the three-dimensional unsteady turbulent flow around a surface-mounted square cylinder of aspect ratio AR = 5 at a relatively low Reynolds number of Re = 500. Experimental studies of similar flows have revealed that the wake structure behind the cylinder changes with the aspect ratio and is affected by both the tip vortices and the boundary layer on the ground plane. The present simulations used two different subgrid-scale models, namely the standard Smagorinsky model and its dynamic formulation. Of special interest are the complex vortex structures in the near wake of the cylinder.

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.
