Abstract

fetched live from OpenAlex

View Video Presentation: https://doi.org/10.2514/6.2023-1492.vid The interaction of a high-energy laser with metals exposed to air is being investigated computationally and experimentally. Particular emphasis is made on a transition to regimes of oxidation, melting, and evaporation of a metal surface. The computational model includes a solution of the Euler equation describing plume formations coupled to a material model accounting for melting and evaporation. A comparison of melting dynamics under normal atmospheric pressure and under vacuum is made. The model includes the possibility of oxide film formation on the surface of a metal. It is found that a thin oxide film can substantially change the evaporation dynamics and surface temperature during the interaction of materials with a high-energy laser.

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.
