Description
Near-wall full Reynolds stress models (FRSMs) were implemented in an implicit, incompressible full Navier-Stokes algorithm. The method was applied to flow in a 3-D duct with significant curvature induced secondary motions as well as 2-D and 3-D turbine cascade flows. FRSM computation of such flows, provides several numerical challenges germane to the very highly clustered near-wall meshes required, and to the incorporation of FRSMs themselves. Several stabilization procedures have been deployed within the scheme, which enable convergent solutions to large scale flow simulations of engineering interest. This paper summarizes the numerical strategies employed. it is shown that near-wall FRSM convergence rates commensurate with those of two-equation models are obtained.
