What is Airflow Modeling Over Ahmed Body about?

The document summarizes a study investigating airflow over an Ahmed body using computational fluid dynamics (CFD) models. It compares the performance of several turbulence models, including k-ε, k-ε-v2, and full Reynolds stress models. The k-ε-v2 model was found to be more accurate than other models for cases with separation and reattachment. A wall function was introduced for the k-ε-v2 model to avoid divergence with fine meshes. Numerical results agreed well with experimental data.
