Abstract
Bias acoustic liners have been investigated by a number of researchers and demonstrated to have acoustic benefits. However while research has concentrated on the acoustic aspects of the liner, little research has directly investigated its heat transfer properties. A three dimensional numerical investigation of the fluid flow and heat transfer properties of a single honeycomb cell was carried out in order to develop an understanding of the flow and heat transfer properties of the bias acoustic liner. Experimental measurements of fluid flow and heat transfer properties of an acoustic liner sample were also carried out in order to validate the numerical solution. The experimental results were found to give lower values of heat transfer coefficient at low flow rates when compared with the numerical solution. The numerical solution for pressure loss agreed with Kutscher’s findings. The experimental results agreed with the traditional expression for pressure loss across abrupt expansions.

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
