Evaluation of an improved mixing plane interface for OpenFOAM
Bibliographic record
Abstract
A mixing plane interface provides a circumferentially averaging rotor-stator\ncoupling interface, which is extremely useful in practical turbomachinery simulations. It\nallows fundamentally transient problems to be studied in steady-state, using simplified mesh\ncomponents having periodic properties, and with the help of a multiple reference frames\n(MRF) approach. An improved version of the mixing plane interface for the community-driven\nversion of OpenFOAM is presented. This new version of the mixing plane introduces a perfield,\nuser-selectable mixing option for the flow fields at the interface, including the possibility\nto use a mass-flow averaging algorithm for the velocity field. We show that the quality of the\nmass-flow transfer can be improved by a proper selection of the mixing options at the\ninterface. This paper focuses on the evaluation of the improved mixing plane interface for\nvarious steady-state simulations of incompressible flows, applied to a simple 2D validation test\ncase, and to more complex 3D turbomachinery cases.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
