Local dynamic perturbation effects on amplitude modulation in turbulent boundary layer flow based on triple decomposition

Local dynamic perturbation effects on amplitude modulation in turbulent boundary layer flow based on triple decomposition

This work studies amplitude modulation (AM) of a turbulent boundary layer flow perturbed by a wall-mounted piezoelectric (PZT) actuator. Hot-wire measurements were executed downstream of the PZT actuator working at a certain frequency but several different amplitudes. Turbulent nonlinear fluctuation...
