dc.description.abstractA computational study of the impact zone of a wall jet with a boundary layer was performed for a wide range of velocity ratios, VR, from 0.065 to 0.2. A ground vortex is formed and for intermediate velocity ratios the flowfield exhibits an oscillating behavior. The location and size of the ground vortex is almost constant during the complete sequence of oscillation, but secondary vortexes may also appear. For the case of very low velocity crossflow (small VR) the computations exhibit a stationary solution, which is in agreement with previous numerical and experimental results. For strong crossflows (large VR) the flow is also stationary, although there is a transition regime of some unsteadiness without any secondary vortex present.pt_PT
