The objective of the work described in this paper was to identify differences in the flow fields immediately downstream of air-jet and vane vortex generators. The flows were assumed to be incompress- ible and fully turbulent and were soled using the finite volume, Navier-Stokes cod eCFX 4 (CFDS, AEA Technology, Harwell) on a Non-orthogonal, body-fitted grid using the k-ε turbulence model and Standard wall functions.
