Simulation of turbulent flows using an algebraic Reynolds stress model with universal wall functions

A New Scalar Reynolds Stress Model For Non-Isothermal Wall Bounded Turbulent Flows

The present investigation concerns the development of advanced scalar turbulence modeling approaches and their application to the calculation of non-isothermal wall-bounded flow phenomena. A new scalar modeling technique based on scalar turbulent scales is proposed and implemented at a second-order modeling approach. Instead of the classical analogy concept between the mechanical and the scalar...

A Review of Reynolds Stress Models for Turbulent Shear Flows

A detailed review of recent developments in Reynolds stress modeling for incompressible turbulent shear ows is provided. The mathematical foundations of both two-equation models and full second-order closures are explored in depth. It is shown how these models can be systematically derived for two-dimensional mean turbulent ows that are close to equilibrium. A variety of examples are provided t...

A Galilean Invariant Explicit Algebraic Reynolds Stress Model For Curved Flows

A Galilean invariant weak-equilibrium hypothesis that is sensitive to streamline curvature is proposed. The hypothesis leads to an algebraic Reynolds stress model for curved ows that is fully explicit and self-consistent. The model is tested in curved homogeneous shear ow: the agreement is excellent with Reynolds stress closure model and adequate with available experimental data. This research ...
