CFD MODELLING OF SYNTHETIC JETS IN A BOUNDARY LAYER AT ADVERSE PRESSURE GRADIENT

The flow field experimentally realized by the wind tunnel for the investigation of the control of boundary layer separation by synthetic jets is numerically modelled. Results of the simulations show good agreement with facts in experiment and some features of the flow control are discussed.
