Accuracy of Turbulent Closure Models in Calculation of Thrust of a Low Reynolds Number Airfoil Used as a Propeller

Unlike in the case of high Reynolds number airfoil, selecting a turbulent closure model for low airfoil is still challenge. A used not necessarily suitable due to presence separation bubbles airfoil. In this study, we two simple models, Spalart-Allmaras and k- , calculating thrust coefficient as propeller determine their accuracy. It was found that there significant discrepancy between numerical calculation results by both experimental data. The little more accurate than model.
