review text: We investigate the effect of surface waviness on boundary-layer transition in two-dimensional subsonic flow. The mean flow is calculated using an interacting boundary-layer procedure, thereby accounting for viscous-inviscid interaction. Then, the linear parabolized stability equations are used to compute Tollmien-Schlichting (TS) wave amplification. As expected, wall waviness is found to destabilize TS waves. This effect is quantified by examining parameters such as wave height, wave length, wave number, wave location, unit Reynolds number, compressibility and pressure gradient and then comparing the results against those obtained in the absence of waviness.
