Abstract

[The linear stability of the Blasius boundary layer which is a quasi-parallel rather than a strictly parallel flow is addressed in this chapter. At high Reynolds numbers, the wall-normal velocity V is small and the growth of the boundary layer is slow compared to distances characteristic for the laminar–turbulent transition induced by small disturbances. Hence, it is not too much surprising that the parallel-flow approximation works quite satisfactorily for two-dimensional waves observed in experiments.]
