Induced Flow Field by an Array of Four Synthetic Jet Actuators Issued in a Quiescent Surrounding
Bibliographic record
Abstract
The induced flow by an array of four synthetic jet actuators with rectangular orifices with a fixed aspect ratio and a fixed centre-to-centre spacing of 8 mm between the jets, at a constant Reynold number (Re) of 660, and three frequencies, that define the Strouhal number (St), is studied experimentally.Five phase differences (Δ𝜙) from 0° to 180° are applied between the actuators on the far right and the far left and the two middle ones.It is shown that the induced flow field is strongly influenced by the Strouhal number, and phase difference between the actuators.Phase differences of Δ𝜙 = 45°, and 90° show constructive interaction between the induced flows by the array of actuators.For the higher Strouhal numbers the results indicate less decay in the time averaged velocity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
