Abstract

fetched live from OpenAlex

In this work, both fully implicit time-domain and nonlinear frequency-domain methods are used to compute aeroelastic solutions in transonic flows. Specifically, flutter boundaries for a two-dimensional NACA64A010 airfoil are calculated and compared with preexisting numerical results. The second-order backward-difference time-accurate scheme will serve as our numerical benchmark when determining the computational efficiency of the nonlinear frequency-domain method. Comparable results between the time-domain and nonlinear frequency-domain approaches will further justify the nonlinear frequency-domain method as an efficient alternative to the study of unsteady periodic problems. A temporal resolution study will establish the required number of modes or time steps per period required for unsteady transonic flows.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
