Unsteady Wake And Dynamic Characteristics Of Flow Past Two Inline Circular Cylinders
Bibliographic record
Abstract
Open-Source Field Operation and Manipulation (OpenFOAM 7) software, has been used for a two-dimensional (2D) numerical computations, to study unsteady wake characteristics in flow past two inline stationary circular cylinders.The solver (icoFoam) employs a finite volume based method (FVM) for discretization and computations.Computations are executed for the range of Reynolds number (Re) from 100 to 250 and for the range of inter-cylinder spacing (S) from 2 to 5. Effects of S and Re on the wake flow behaviour and dynamic coefficients for the cylinders have been presented.Four different values of S and Re have been considered which show influence on both the wakes, with stronger effect on the wake behind the downstream cylinder.To analyse unsteady wake characteristic, the time series of transverse velocity component has been used.In addition, the lift signals of both the cylinders have been analysed to study the phase dependence on S and Re.

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.
