In this paper we present a simplified form of the local correlation-based zero-equation kγ transition model (Sandhu, Jatinder Pal Singh, "Local-Correlation Based Zero-Equation Transition Model for Turbomachinery," Proceedings of the ASME 2019 Gas Turbine India Conference, Volume 1: Compressors, Fans, and Pumps; Turbines; Heat Transfer; Structures and Dynamics) derived from the one-equation γ transition model (Menter, F. R., Smirnov, P. E., Liu, T., and Avancha, R., “A One-Equation Local Correlation-Based Transition Model,” Flow, Turbulence and Combustion, vol. 95, 2015, pp. 583–619). The new model is easy to implement and saves computational time and memory. The proposed model is validated against the standard T3 series flat plate test cases (with and without pressure gradient), Hultgren and Volino series, Aerospatial A-Airfoil and the Eppler-387 airfoil. Results indicate that the transition predicted with the new model is similar to the one-equation γ transition model in most cases and compares reasonably well with experimental data. The predicted transition is also gradual in some cases and the method provides a savings in computational memory and time (in most of the flat-plate test cases) over the γ model
