(YIP) Exploiting the Non-linear Interactions within Wall Turbulence for Flow Control
Abstract
To characterize the nonlinear interactions of the large-scale motions within turbulent boundary layers with the smaller scales in the flow through systematic perturbation of the large-scales. These perturbations will alter the energy of the large-scales as well as its distribution across wavelengths. This will establish the relationship between the energy of the large-scales in the flow and its interaction with the small-scales, while characterizing the associated modulation effect. This will enable the scaling of sensors/actuators needed to implement this control strategy. This knowledge could be used to implement such a control strategy that targets the large-scale motions encapsulated within the boundary layer to selectively increase or reduce the wall shear stress
