A Modified k-ω Turbulence Model for Finite-Element CFD
2018 Fluid Dynamics Conference, 2018•arc.aiaa.org
A modified-turbulence model is presented, with the goal of enhancing compatibility with
finite-element discretizations. The proposed model alterations are designed to increase
solver robustness and improve convergence characteristics by circumventing numerical
issues that arise in and near non-physical states. The modified-turbulence model is tested
within HPCMP CREATE™-AV Kestrel component COFFE. Results for multiple benchmark
turbulence model cases are presented to assess the validity of the model.
