Abstract
Abstract This contribution discusses the influence of fluid forces, stemming from compliant, contact‐free annular rotor seals, on the steady state stability and bifurcation behaviour of a rotor. The model used in this work consists of a Laval‐Rotor where the disc runs in a turbulently streamed seal. The compliance of the seal is reduced to a visco‐elastically supported outer seal ring. In order to account for the fluid seal forces the Childs‐Hirs‐model is used. An investigation of the eigenvalues shows that the compliance of the seal support may lead to a significant increase in the stable operating range. A stability‐loss via Hopf‐ , Hopf‐Hop f or secondary Hopf‐ Bifurcations can occur depending on the system parameters. (© 2015 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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
