Wave cancellation in jets with laminar and turbulent boundary layers: The effect of nonlinearity
Igor A. Maia, Peter Jordan, André V. G. Cavalieri
Abstract
In this work we perform real-time control of forced jets based on a wave-cancellation scheme. Building on previous work on control of stochastic disturbances, here we carefully characterize the performance and limits of this control approach with the onset of nonlinearities. The breakdown of linearity and its impact on control performance are illustrated through a thorough comparison between jets with laminar and turbulent boundary layers.
