Abstract

fetched live from OpenAlex

Experiments of H2 /air premixed combustion were carried out in a micro Laval nozzle with inner throat diameter of 1?mm and inlet/outlet diameter of 2?mm. This paper focused on the stable combustion range, wall temperature, flame starting position and flame feature. The experimental results show that the stable combustion range is extended significantly compared with the combustion in circular and T-type tube because of the converging-diverging structure, and flame can stabilize in this region with appropriate equivalence ratio as the inlet flow rate varies in the range of 3.4?m/s to 41.4?m/s. Wall temperature and flame starting position are both affected by the inlet flow rate and equivalence ratio(?). The maximum wall temperature is observed at the fuel-rich condition of ????1.4. Flame starting position moves downstream with the increase of flow rate. But it moves upstream firstly, then downstream, with the increase of equivalence ratio. By optimizing the selection of equivalence ratio and flow rate, the temperature and flame location can be controlled in the nozzle, which provides guidance for the design and improvement of micro-propulsion system.

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.
