Abstract

fetched live from OpenAlex

Abstract It is well known that a special attention is necessary to infer process information of a spouted bed at full‐column using data from semi‐cylindrical vessels. In this work experimental data are obtained from a semi‐cylindrical spouted bed for comparison with CFD simulations performed using a 3D simulation scheme. The purpose of this paper is to contribute on the discussing about the influence of the flat wall in the solid behaviour inside the semi‐cylindrical vessel by comparing numerical results with experimental data. Simulated results of fountain height, spout diameter and particle velocities inside the bed are compared with image data obtained from a semi‐cylindrical column. The simulations were accomplished using the commercial package FLUENT 6.3.26.

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.

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.
