Abstract

fetched live from OpenAlex

Abstract Simulations of transitional and turbulent flows of purely viscous thixotropic liquids in stirred tanks have been performed. The simple thixotropy model employed is based on the notion of a network in the liquid with an integrity that builds up with finite rate under quiescent conditions and breaks down under liquid deformation. We solve a transport equation for the network integrity which is two‐way coupled to the lattice‐Boltzmann‐based flow solver. The liquid's time scale characterised by the dimensionless Deborah number demonstrates to have profound impact on the level of mobilisation and the flow patterns in the mixing tanks, especially if the time scale of the liquid is of the same order as the circulation time in the tank. It also is shown to what extent increasing the impeller speed improves mobilisation.

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.
