Abstract : Existing methods for predicting transition from laminar to turbulent flow in boundary layers on smooth bodies of revolution immersed in axisymmetric flows with very low background turbulence are examined critically. Several are compared to available experimental results. A new correlation is then proposed which incorporates not only the usual effect of pressure gradients but also the effect of axisymmetric spreading of the boundary layer on the location of transition.
