Originální abstrakt

In this paper, numerical investigations are performed to analyze the flow behavior over NACA0015 and the efficiency of vortex generators VGs (triangular and rectangular in shape) and continuous jet as passive and active control devices are evaluated. The unsteady Reynolds-averaged Navier-Stokes equations of the turbulent flow are solved using, k-ω SST provided by the ANSYS CFX-CFD code. The model presented in this paper is a comprehensive representation of the information available in the literature. Validation shows a qualitatively good agreement with previous researches, and almost all flow structures are well reproduced by the computation. The results confirm that the vortex generators can influence flow separation and thus improve the aerodynamic performance of NACA0015 airfoil. The results show that the triangular VGs that include jet are more efficient than the triangular and rectangular VGs.
