| Abstract | ||
| An experimental study of the two-dimensional laminar -transitional boundary layer beneath a turbulent free stream is presented . It is shown that the mean velocity profiles develop a wavy shape prior to transition that contains local points of inflexion. These waviness is made clear by plotting the deviations of the profiles from the Blasius solution of the laminar bounary layer which is shown to be valid even for a turbulent free stream . | ||
