Stability of blasius boundary-layer flow interacting with a compliant panel: American Society of Mechanical Engineers (ASME), in Proceedings of the 2014 Pressure Vessels and Piping Conference, Jul 20–24 2014, Paper No. PVP2014-29094, pp. V004T04A081. California: American Society of Mechanical Engineers.

We develop a model to study the fluid-structure interaction (FSI) of a compliant panel with a Blasius boundary-layer flow. We carry out a two-dimensional global linear stability analysis modeling the flow using a combination of vortex and source boundary-element sheets on a computational grid while the dynamics of a plate-spring compliant wall are represented in finite-difference form. The system is then couched as an eigenvalue problem and the eigenvalues of the various flow-and wall-based instabilities are analyzed for two distinct sets of system parameters. Key findings are that coalescence - or resonance - of a structural eigenmode with either the most unstable flow-based Tollmien-Schlichting Wave (TSW) or wall-based travelling-wave flutter (TWF) modes can occur. This renders the convective nature of these instabilities to become global for a finite compliant wall, a phenomenon that has not hitherto been reported in the literature.
