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...
