Abstract

fetched live from OpenAlex

The phase rule states that a fluid element is determined locally by c+1 independent intensive variables when there are c components. In solving the Boltzmann equation for gas transport coefficients, the standard procedures involve only c independent gradients of intensive variables for the local properties (exclusive of the convective motion). This paper addresses this disparity and proposes an alternative set of gradients when solving the Boltzmann equation. The consequence is added terms in the expressions for the thermal diffusion coefficients. As well, the standard expression for the binary diffusion constant is identified as being valid only at constant total density. Irreversible thermodynamics is used as a reference base for comparing the alternate formulations.

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.
