This paper provides a review of the current findings in receptivity for subsonic/transonic flows, including a discussion of the origin of the concept via Mark Morkovin, a remarkable aeronautical engineer, educator, and colleague. Disturbances external to the boundary layer–whether freestream sound or vorticity–can interact with surface roughness, the leading edge, or other inhomogeneities and enter the boundary layer as steady and/or unsteady fluctuations of the basic state. This process establishes the initial conditions of disturbance amplitude, frequency, phase, and scales for the breakdown of laminar flow. The past decades have seen considerable progress in the understanding of receptivity mechanisms guided by the roadmap (Morkovin et al.1).
