title = "Assessment of filtered-based RANS turbulence model for unsteady separated flow prediction",
abstract = "The k-ε two-equation model is one of the most widely used Reynolds-averaged Navier- Stockes (RANS) approach for turbulent flow computations. Well-recognized deficiencies are associated with these models when treating steady and time dependent separated flows. The objective of this study is to investigate a filtered-based RANS k-ε two equation model in an effort to improve the predictive capability of the current RANS-based engineering turbulence closures. The model is assessed on a variety of test cases, a square cylinder1 and a surface-mounted cube2 are chosen to examine transient highly separated wake flows. Multiple grid levels and multiple sub-filter sizes are used for sensitivity analysis. In comparison to the presented k-ε model, overall, the filtered-based model is shown to improve the predictive capability considerably.",
