Environment and Receptivity,
Abstract
In an environment where initial disturbance levels are small, the transition Reynolds number of a boundary layer is very much dependent upon the nature and spectrum of the disturbance environment, the signatures in the boundary layer of these disturbances and their excitation of the normal modes 'receptivity', and finally the linear and nonlinear amplification of the growing modes. This lecture reviews the progress in understanding receptivity to free stream vorticity and acoustic disturbances. It also outlines the techniques of the initial value problem, which promises to be a significant additional tool for providing guidance toward the resolution of receptivity issues. (Author)
