Current numerical simulations investigate subsonic flow around the NREL’s S807 airfoil without an incident angle at Reynolds numbers near 2.8∙105. This work is devoted to the assessment application of various turbulence models for a numerical simulation of the formed flow around the streamlined body in commercial software ANSYS CFX. Namely, we applied Shear Stress Transport fully turbulent model (SST0, Baseline Reynolds stress model (BSL RSM) and SSG RSM for the computation of velocity deficit, degree of turbulence anisotropy, Reynolds stress components, and aerodynamic performance of the airfoil. The obtained results were validated on the basis of hot wire measurement data. Additionally, in order to validate the obtained results, a comparison with the hot-wire experimental data was also carried out. The obtained experimental and calculated data showed some differences in the wake topology. For example, in the case of hot-wire data, there is a smaller velocity deficit and a wider area of perturbation.
