Abstract
In this paper, the three-dimensional (3D) flow of a jet in a crossflow was investigated. This is a numerical study based on a vortex particle method. In order to account for the lower length scales, a crude LES turbulence model was implemented together with a regridding procedure. The numerical simulation was done with an injection ratio R inj = W jet/U ∞ = 4.0. The code was run until an averaged steady state of the jet was reached. The resulting vortex structures were shown to be consistent with previously published analyses of the flow, from both experiments and numerical simulations. In particular, the onset of counter-rotating vortex pairs (CVP) was also investigated.
