N2 - This paper introduces a one-equation transition model based on the one-equation Wray-Agarwal (WA2018) turbulence model and an algebraic intermittency term γ. The newly developed model is validated by computing benchmark ERCOFTAC test cases, namely T3A, T3B and T3A- for transitional flow over a flat plate with different free stream turbulent intensity and zero pressure gradient, and T3C series cases of flow over a flat plate under pressure gradient and different free stream turbulence intensity, and transitional flow past S809 airfoil. The new model has capability to predict the location where the transition occurs and its overall performance is satisfactory. The model is very efficient being only a one-equation model compared to Langtry-Menter four-equation transition SST model.
