Innovative Model for Flow Governed Solid Motion based on Penalization and Aerodynamic Forces and Moments
Bibliographic record
Abstract
This work proposes a fluid-solid interaction model. It is formulated for a laminar flow modeled by the incompressible Navier-Stokes equations in which we consider the presence of a rigid moving solid. The model is formulated inside an immersed boundary method based on a penalization technique. The penalization technique imposes the body effects on the flow. The velocity field is extended inside the solid region and a penalty term enforces the rigid motion inside the solid region. This technique offers a great flexibility to modify the geometry of the solid. The forces and angular momentum needed for the fluid-solid interaction model are computed with an innovative method suitable for the penalized equations method. The method is validated successfully for an oscillating airfoil in large flapping motion. Effects of different geometries on aerodynamic coefficients can then be explored. The fluid-solid interaction model is also verified for solid motions governed by the flow, such as falling cylinder and plate.

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.
