Abstract
Fixed-bed regenerator (FBR) is one type of air-to-air energy exchanger used to reduce the energy consumption in HVAC systems. Use of corrugated plates is one way to improve the heat transfer performance of FBRs. In this study, the sensible effectiveness and average heat transfer coefficient of an FBR with corrugated plates are compared with that of an FBR with parallel plates. The effectiveness of corrugated plate FBR is experimentally evaluated in a small-scale test facility. A validated numerical model is used to predict the performance of the parallel plate FBR. The average heat transfer coefficient of corrugated FBR is determined from the measured data and Kays and London regenerator correlation. The heat transfer coefficient and effectiveness of corrugated plate FBR are 150% and 37% higher than that of parallel pate FBR at a Reynolds number of 1450. Results from the present study can be used to design FBRs and evaluate their effectiveness for a range of Reynolds numbers from 500 to 1450.

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
