Abstract
Previous theoretical work has led to the development of methods for optimizing compliant-wall properties to achieve the greatest possible transition delay for flat-plate boundary-layer flows. It was found that the optimum wall properties for locally reducing the growth of disturbances depend quite strongly on the Reynolds number. This suggests that it would be advantageous to use multiple-panel walls with each compliant panel optimized for a particular Reynolds number range. Accordingly, the optimization procedure is extended to two-panel compliant walls, and the optimum wall properties are determined that correspond to the greatest transition delay
