متن کاملInstabilities in turbulent boundary layers
An investigation of a model of turbulence generation in the wall region of a turbulent boundary layer is made through direct numerical simulations. The model is based on the instability of a streak. First, a laminar boundary layer disturbed by a continuous blowing through a slot is simulated in order to reproduce and further investigate the results reported from the experiments of Acarlar & Smi...
متن کاملInteraction of Synthetic Jets with Laminar and Turbulent Boundary Layers
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 resea...
متن کاملControl of turbulent boundary layers
The objective of this paper is to give an overview of recent progress on boundary layer control made by the author’s research group at University of California, Los Angeles. A primary theme is to highlight the importance of a certain linear mechanism and its contribution to skin-friction drag in turbulent boundary layers—and the implication that significant drag reduction can be achieved by alt...
