Acoustic Receptivity in Boundary Layers with Surface Roughnessristic heart-shaped disturbance wedge downstream from the roughness. This behaviour is consistent with the numerical and asymptotic work of other authors, who also predict the off-centreline peak amplitude that is observed several wavelengths downstream from the roughness.

Effect of Leading-edge Geometry and Aerodynamic Loading on Receptivity to Acoustic Disturbancesint at which the mean boundary-layer flow separates, a marked increase in receptivity coefficient is observed. Obliquely incident acoustic waves are found to produce much higher receptivity levels than parallel waves.

Study of 3D Wall Roughness Acoustic Receptivity on an Airfoilesults are compared with Direct Numerical Simulations based on a vorticity-velocity formulation of the complete Navier-Stokes equations and a new embeded wall model. Good overall agreement is achieved.

A Causal Stability Analysis of the Boundary Layer over a Compliant Wallull study of this behaviour is made, including the interesting limit in which the boundary layer is very thin on the scale of the plate bending waves. In the simpler case of uniform flow we also derive model nonlinear equations to describe the evolution of certain negative energy waves.

Non-Parallel Receptivity and the Adjoint PSEhe scattering of an acoustic wave onto a hump. It is shown that acting on the flow with a source of streamwise momentum and at the wall with fluid injection and suction produces large responses. The flow sensitivity results are keys to an effective control of the instability.
