Comparison of Asymptotic Prediction Methods for Boundary-Layer Receptivity
Orr-Sommerfeld theory and triple deck theory are compared for receptivity problems. Predictions for the perturbed velocity field are obtained and compared with experimental results for one of the simplest cases of receptivity, namely an isolated oscillating roughness element on a flat-plate.
