The modified algebraic model of Fürst et al. (2013) connected with the EARSM model of Hellsten (2004) gives acceptable results in all tested cases. The k-kL-omega model predicts in some cases the transition onset shift downstream which leads to the laminar separation in the decelerated flow and to the transition in the separation bubble. Moreover, comparison with XFOIL program based on the e^n method was drawn.
