| Summary: | <p>The primary objective of this study is to validate and/or identify issues for
available numerical methods and turbulence models in OpenFOAM 2.0.0. Such a study
will provide a guideline for users, will aid acceptance of OpenFOAM as one of the
research solvers at institutions and also guide future multidisciplinary research using
OpenFOAM. In addition, a problem of aerospace interest such as the flow features and
vortex breakdown around a VFE-II model is obtained for SA, SST RANS and SA-DDES
models and compared with DLR experiment. The available numerical methods such as
time schemes, convection schemes, P-V couplings and turbulence models are tested as
available for a fundamental case of a backward facing step for RANS and Hybrid RANSLES
prediction of fully turbulent flow at a Reynolds number of 32000 and the
OpenFOAM predictions are validated against experimental data by Driver et.al and
compared with Fluent predictions.</p>
