A scheme for generating boundary layers is described and applied to an infinite swept wing model with wavy surface deformations. Steady laminar mean flow is extracted directly from solutions of the Navier–Stokes system of equations, which is validated against computations of a compressible boundary-layer method. Furthermore, the routines capture separated boundary-layer profiles, overcoming the constraints of the conventional methods. The stability of crossflow disturbances is investigated using both the parabolized stability equation and linearized Navier–Stokes methods, and the effect of chordwise waviness of variable wavelength, amplitude, and phase is considered. Wavy surfaces are found to influence the growth of crossflow disturbances, suggesting that the onset of transition may also be affected by the variations in the surface geometry.
