Effect of the free-stream turbulence on the bi-modal wake dynamics of square-back bluff body

The effect of a free-stream turbulence intensity level on the wake dynamics of a square-back Ahmed body is modeled using the improved delayed detached eddy simulation at Re = 9.6 × 10 4. The center of pressure, pressure gradient on the base surface, and the barycenter of the momentum deficit on the...
