Effect of Downstream Flapping Plate on the Flow Field Characteristics behind a Circular Cylinder
Bibliographic record
Abstract
Two-dimensional numerical investigations of flow characteristics behind a circular cylinder in the presence of a flapping plate mounted in the wake have been carried out in the present study. The flapping frequency of the plate has been varied in the range from 0.6 to 1.4 times the vortex shedding frequency behind single stationary circular cylinder in the presence of a stationary plate. The gap between the cylinder and the plate is considered to be 1D, 2D and 3D. The maximum amplitude of the tip of the plate has been fixed to be 0.3D (D being the diameter of the cylinder) for each of the frequency ratio for fixed value of Reynolds number (Re) equal to 100. The length of the plate has been chosen equal to cylinder diameter. The dynamic effects and the behaviour of vortex shedding behind the cylinders have been studied elaborately. Effect of fixed amplitude and varying frequency ratio of the cylinder on wake flow behaviour has been presented in the form of vorticity contours, lift, drag and Strouhal number (St) plots. The dynamic forces as well as the flow structure behind the plate are found to be modified in the presence of the flapping 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.
