The Wray-Agarwal Algebraic Transition (WA-AT) model has been validated for various ERCOFTAC flat plate cases and airfoil cases. The NACA 4412 is an asymmetric airfoil with unique laminar to turbulent transition characteristics. The NACA 4412 was chosen as a validation case for an undergraduate Independent Study. This paper presents the results of the validation of the Wray-Agarwal Algebraic Transition model for the NACA 4412 airfoil. The one equation WA-AT model shows similar agreement as the four-equation k-ω-SST-γ-Reϴ transition model with experimental data at 3*10^6 Reynolds number for lift coefficient prediction, drag polar, and transition location predictions for an angle of attack sweep from 0 to 18 degrees.
