Abstract
A multidisciplinary optimization procedure is developed for an internal and external cooled gas turbine blade. The goal is to control the heat transfer on the blade surface while maintaining the total pressure loss and cascade mass flow rate along with blade geometric constraints. The flow is solved using a finite volume solver for 2D NavierStokes equations while the temperature distribution of the blade interior is obtained by a finite element solver. The FV and FE solvers are coupled through a loose coupling method and by the exchange of the boundary condition. For the optimization purpose a continuous adjoint method is employed for 2D compressible Navier-Stokes flows and the corresponding adjoint boundary conditions are derived. A characteristic based approach is utilized in developing the adjoint boundary conditions for the sake of consistency with flow boundaries. The objective function is optimized with respect to the cascade mesh points, cooling hole location and the angle of injection as design variables.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
