Abstract

fetched live from OpenAlex

This work aims to evaluate the possibility of adding obstacles to ducts with isothermal flows and their effects on the performance of the flowfield. This literature review was performed based on several articles exploring obstacles and their geometries inside ducts and chambers or channels and analyzing the obstacle distribution in a nozzle. The main utility of the obstacle is in the pipes and boilers of the metal-mechanical and petrochemical industry. In these industries, results are mostly positive since the obstacles allow manipulating the temperature inside channels and on their walls. Besides, they are correlated to increasing the acceleration of the exhaust gases and turbulence of the flow. In addition, an optimal preliminary nozzle geometry was found for applications in the aerospace industry. However, this information is useful for other applications. Thus, the possible use of obstacles in cases where the combustion reactions are considered seems promising, indicating an excellent opportunity to further research this topic in more specific areas.

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.
