First instability and structural sensitivity of the flow past two side-by-side cylinders

First instability and structural sensitivity of the flow past two side-by-side cylinders

The onset of two-dimensional instabilities in the flow past two side-by-side circular cylinders is numerically investigated in the ranges $0.1\leq g\leq 3$ and $\mathit{Re}
