Abstract

fetched live from OpenAlex

The lattice Boltzmann (LB) method is becoming an increasingly important technique for the simulation of problems involving the interaction between acoustic and fluid fields. New LB algorithms allow the representation of moving boundaries at low Mach numbers. In this work we present the implementation of a hybrid model involving one such LB algorithm coupled to a finite difference scheme to simulate the fluid-structure interaction at the reed of a two-dimensional clarinetlike system. The results of the simulation for different input pressures and reed parameters are compared with the results provided by the related literature. [The first author was supported by CAPES (Brazil).]

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.
