Wake dynamics and transition of the flow around a square cylinder sliding along a wall

The dynamics and transitions of the flow past a square cylinder sliding along a wall are investigated numerically for Reynolds numbers (Re) between 20 and 300, and gap distances (G) between 0.05 and 1.0 side length of the square (D). The presence of the wall is found to fundamentally alter the wake dynamics and three-d...
