Abstract
The emerging field of thermoacoustic cooling systems (TACS) has been explored in recent years, combining the disciplines of acoustics and thermodynamics to provide an alternative to mainstream cooling technologies. This hybridised system allows a system of travelling or standing waves to absorb and release thermal energy at different points spatially, which is then harnessed to produce a cooling effect. This meta-analysis will focus on analysing parameters such as stack plate spacing and selection of a working fluid, in order to optimise the system. As this will directly impact the temperature gradient, as the temperature gradient is the core operator in the cooling process. The above parameters were examined with a combination of comparative and normalisation techniques, to synthesise data from varied experimental sources and produce accurate conclusions. The parameters investigated had differing effects on the system with regards to COPR and maximum cooling power, due to cooling power and input acoustic power increasing at different rates. The meta study concluded that a ratio of parallel-plate stack spacing to thermal penetration depth of (equation) was ideal for maximising cooling load, where as a ratio of approximately (equation) was ideal for achieving maximum COPR.

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
