A Novel Approach to Turbomachinery Blading Design in Three-Dimensional Flow Using Commercial CFD Tools
Bibliographic record
Abstract
An aerodynamic inverse shape design of turbomachinery blading in three-dimensional viscous flow is developed and implemented into a commercial CFD program, namely ANSYS-CFX. It is applied to redesign the rotor blades of an axial compressor stage and an axial turbine stage. The design method is based on specifying one blade parameter, the stacking line (a blade line from hub to tip), and two other parameters such as the blade loading and thickness distribution or the pressure distributions on blade surfaces. This inverse design approach is fully consistent with the viscous flow assumption and is independent of the CFD approach taken. An axial compressor stage E/CO-3 and turbine stage E/TU-3 are analysed and the results thus obtained are assessed against available experimental data. These stages are then inversely designed in order to improve their aerodynamic performance.

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; both teacher heads agree on what is shown here.
