Abstract

The V2F model makes use of the standard k–ε model, but extends it by incorporating near-wall turbulence anisotropy and non-local pressure-strain effects, while retaining a linear eddy viscosity assumption. It has the attraction of fewer equations and more numerical robustness than Reynolds stress models. The model is presented in a form that is completely independent of distance to the wall. This formalism is well suited to complex, 3-D, multi-zone configurations. It has been applied to the computation of two complex 3-D turbulent flows: the infinitely swept bump and the appendage-body junction; some preliminary results for the flow in a U-bend are also presented. Despite the use of a linear, eddy viscosity formula, the V2F model is shown to provide excellent predictions of mean flow quantities. The appendage-body test case involves very complex features, such as a 3-D separation and a horseshoe vortex. The V2F simulations have been shown to successfully reproduce these features, both qualitatively and quantitatively. The calculation of the complex flow structure inside and downstream of the U-bend also shows very promising results.
