Abstract

The interaction between circular synthetic jets and flat-plate laminar/turbulent boundary layers is investigated using CFD simulations in this study. For turbulent boundary layer simulations, large eddy simulation (LES) is applied so as to obtain more accurate flow details. The simulation results are validated using both existing experimental data and numerical results obtained from other researchers, and reasonable agreements are achieved. The simulated vortical structures produced by a circular synthetic jet issued into a laminar boundary layer and a turbulent boundary layer are analysed and compared. Obvious difference is found between the vortical structures formed in those two boundary layers. Meanwhile the effects of the different vortical structures on wall shear stresses are also evaluated to help identify the flow control effectiveness of synthetic jets in different types of boundary layers.
