abstract
1995 (Publisher). All rights reserved. Experiments are conducted to determine the acoustic receptivity in the leading-edge region of a Blasius boundary layer. New measurement techniques are critically reviewed. Receptivity coefficients are determined for two different leading edges under different frequency and speed conditions. It is shown that only a rather narrow band of frequencies generate measurable unstable wave amplitudes. Comparisons are made with existing analyses and DNS.
