A study of the boundary layer transition process
Abstract
A boundary layer smoke tunnel was used in the reported experimental investigation. A study of the three-dimensional nature of boundary-layer instability was conducted with the aid of a vibrating trip wire method. For a study of turbulent spots, the trip wire in the tunnel was removed, and a turbulent spot was initiated by a short pulse of air from a hole in the tunnel floor. This formed a jet normal to the floor. The features of a turbulent spot, as indicated by the observations, are discussed. Additional experiments are proposed to obtain a verification of the assumed characteristics of the turbulent spot.
