“…Numerical work by Murdock (1981) for a parabola in a flow with a parallel acoustic wave also showed a decrease in receptivity as the nose radius was increased. The computations of Lin et al (1992) were for parallel acoustic waves incident on half-ellipse leading edges connected to a flat plate and for super-ellipse leading edges (which avoid the discontinuity in curvature), geometries chosen to match the experiments of Saric et al (1994). For both these geometries there are regions of adverse pressure gradient near the leading edge, as well as the possibility of additional localised receptivity mechanisms (Goldstein, 1985); hence no direct comparisons can be made with the present results.…”

“…When considering a boundary layer over the smooth surface, it is observed that the presence of free stream sound gives rise to unstable waves due to rapid changes in the flow near the leading edge and around non-uniformities of the boundary conditions [1][2][3], [4][5][6][7][8][9]. When a roughness element is placed on the surface, it generates additional regions with strong local changes of the flow which in tum are generators of unstable waves [10][11].…”

“…Saric & Rasmussen (1992) conducted experiments on a flat plate with an elliptical leading edge stuck onto it, but it was noted that the discontinuity in curvature, at the join, produced another region of receptivity. Saric et al (1995) eliminated this problem by using an elliptic leading edge machine drilled onto a flat plate, called a Modified Super Ellipse (MSE), to eliminate any discontinuity, and further experiments were carried out by Saric & White (1998). Fuciarelli et al (1998) and Wanderley & Corke (2001) both computed their respective numerical calculations for the MSE in order to compare their results with those of Saric & White.…”

“…Experimental results on leading-edge receptivity are summarised by Saric & Rasmussen (1992), and Saric et al (1995). Saric & White (1998) considered receptivity on a modified super ellipse (MSE) due to free-stream sound.…”
