Towards a nonlinear eddy-viscosity model based on elliptic relaxation

A phenomenological method has been used to derive a nonlinear constitutive relationship that can be used in conjunction with any eddy-viscosity model utilizing the elliptic relaxation method. While retaining the merits of the elliptic relaxation to model near-wall turbulence, the new model also enab...

description A phenomenological method has been used to derive a nonlinear constitutive relationship that can be used in conjunction with any eddy-viscosity model utilizing the elliptic relaxation method. While retaining the merits of the elliptic relaxation to model near-wall turbulence, the new model also enables the turbulence anisotropy to be faithfully predicted in wall-bounded flows.
