Abstract

This paper reviews and assesses the recent progress toward making the use of compliant walls a practical method of laminar-flow control. Three main areas are covered. First, the current understanding of the vitally important how-induced surface instabilities is assessed. Some new results are included. Then the optimization of multiple-panel compliant walls is considered. New numerical simulation results are included showing that short compliant panels are very effective in suppressing Tollmien-Schlichting waves, It is found that for marine applications appropriately designed multiple-panel compliant walls are capable of suppressing Tollmien-Schlichting waves to indefinitely high Reynolds numbers. Finally, the feasibility of using compliant walls for laminar-flow control in aeronautical applications is assessed. It is found that, although there is no reason in principle why compliant walls cannot be used in air, in practice exceptionally delicate walls are required to obtain the necessary match between the fluid and structural inertias. The resulting lack of robustness for such walls is deemed to make them completely impractical for aeronautical applications.
