On the linear evolution of disturbances in plane Poiseuille flow

The linear evolution of disturbances due to a ribbon vibrating at frequency \(\omega_0\) in plane Poiseuille flow is computed by solving the associated initial boundary value problem in the Fourier-Laplace plane, followed by inversion. A novel algorithm for identifying the temporal modes of the Orr-...
