Abstract

The Wray-Agarwal Algebraic Transition (WA-AT) model has been previously applied successfully to various ERCOFTAC flat plate and airfoil validation cases. The NACA 4412, NLF-0414, and NACA 64(3)-418 serve as additional validation cases due to the presence of transition at certain Reynolds numbers. The one-equation WA-AT model has shown accuracy similar to the three-equations k-ω-SST-γ model and the four equations k- ω -SST-γ−Reθt model in these three asymmetric airfoil applications for Reynolds numbers of 3*10^6, 3*10^6, and 2.5*10^6, respectively. The lift, drag, and skin friction are predicted for all the three airfoils and results are compared to the available experimental and numerical data. The WA-AT model has demonstrated accuracy close to that of the k-ω-SST-γ and k- ω -SST- γ-Reθt models with substantially lower computational cost.
