Turbulence Modeling Resource
The purpose of this site is to provide a central location where Reynolds-averaged Navier-Stokes (RANS) turbulence models are documented. This effort is guided by the Turbulence Model Benchmarking Working Group (TMBWG), a working group of the Fluid Dynamics Technical Committee of the American Institute of Aeronautics and Astronautics (AIAA).
The objective is to provide a resource for CFD developers to: 1) obtain accurate and up-to-date information on widely-used RANS turbulence models, and 2) verify that models are implemented correctly.
This latter capability is made possible through "verification" cases. This site provides simple test cases and grids, along with sample results (including grid convergence studies) from one or more previously-verified codes for some of the turbulence models. Furthermore, by listing various published variants of models, this site establishes naming conventions in order to help avoid confusion when comparing results from different codes.
The site should also help CFD code users to understand and compare the predictions of a variety of models on the fundamental flow problems in the validation database. Note that it is not the intention of this effort to provide validation of turbulence models for a wide range of complex flows for diverse applications. While this would undoubtedly be valuable, it is beyond the scope of what can be supported. Instead, the goal is to provide a set of test cases that illustrate the performance of models for fundamental flows, in order to establish a consistent basis of comparison as a starting point from which a more thorough validation effort for flows of specific interest to users and developers can be conducted.
Finally, the site should serve as a forum for model developers to help disseminate new models to the CFD community.
It is anticipated that this site will be updated regularly as new models and/or verification/validation cases are incorporated and tested. |
