Abstract
This paper extends the widely used second-moment closure of Gibson and Launder so as to be applicable within the near-wall sublayer where viscous effects are substantial. This extension, which allows the usual log-law/local-equilibrium matching to be discarded, enables boundary-layer problems to be tackled where the flow structure in the inner region departs from what is usually termed the universal wall law. Applications are reported of the flat-plate boundary layer and three cases in which strong streamwise pressure gradients are imposed. Agreement with experiment is better than when the simpler A-e model is adopted.
