The V2F model makes use of the standard k-epsilon 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 at
traction of fewer equations and more numerical robustness than Reynolds str
ess 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, mu
lti-zone configurations. It has been applied to the computation of two comp
lex 3-D turbulent flows: the infinitely swept bump and the appendage-body j
unction; some preliminary results for the flow in a U-bend are also present
ed. Despite the use of a Linear, eddy viscosity formula, the V2F model is s
hown to provide excellent predictions of mean flow quantities. The appendag
e-body test case involves very complex features, such as a 3-D separation a
nd a horseshoe vortex. The V2F simulations have been shown to successfully
reproduce these features, both qualitatively and quantitatively. The calcul
ation of the complex flow structure inside and downstream of the U-bend als
o shows very promising results.
