Turbulence: Near-Wall Treatment & Turbulence Models Guidelines

This lecture covers the near-wall treatment in turbulent flow simulations, comparing wall function and near-wall model approaches. It also discusses guidelines for choosing turbulence models, variations, near-wall treatments, model parameters, and appropriate mesh. A case study on turbulent flow past a blunt flat plate is presented, highlighting the importance of model selection. The instructor emphasizes the complexity of turbulent flows, the hierarchy of simulation approaches, and the challenges in modeling turbulence. Validation of flow solutions is crucial for accuracy, and the lecture concludes with references for further study on turbulence and its modeling.
