WebJul 1, 2010 · Abstract. A model-based description of the scaling and radial location of turbulent fluctuations in turbulent pipe flow is presented and used to illuminate the scaling behaviour of the very large scale motions. The model is derived by treating the nonlinearity in the perturbation equation (involving the Reynolds stress) as an unknown forcing ...

Webfollowing analysis is also applicable to boundary layers on axisymmetric objects provided that the boundary layer is thin enough that local curvature terms are always negligible (i.e. !(x)R(x)!1). The boundary layer thickness grows with !(x)L<<1 x but is small with respect to the length scale of the surface . We proceed as follows:
