Abstract
A modified t-ω 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 t-ω 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.
