Abstract

fetched live from OpenAlex

Abstract In 2016, Montreal Protocol Kigali Amendment stipulated that developed countries should reduce the consumption and production of HFCs from 2019 and that developing countries should start the reduction in 2029. New alternative refrigerants should have lower GWP to reduce negative effects on the environment. Propane (R290) is an efficient and clean energy fuel. It not only has a high calorific value, but also has the advantages of large reserves and light weight. However, it has high flammability, so it has not been applied in production extensively. Therefore, despite the possible applications for propane as a refrigerant, a limited quantity of heat transfer information can be found in the open literature. In this study, the boiling heat transfer of R290 in 1.5, 4.0 and 6.0 mm smooth tubes was experimentally studied in the existing literature, and draws some conclusions with the usage of comparative analysis method.

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.
