Flow around an oscillating circular cylinder. Regime A (Tatsuno & Bearman 1990).

The visualization is done using massless particles placed in a stream. Numerical modeling was performed in the OpenFOAM package. Oscillation parameters beta=35, KC=4.5. See also https://www.researchgate.net/publication/326195495_Numerical_Analysis_of_Secondary_Flows_Around_An_Oscillating_Cylinder
