摘要：

The wake generated by a vertical axis wind turbine is investigated experimentally and numerically. The experiments were conducted in an open-jet wind tunnel. The selected velocity is 4.83 m/s. In this study, a model of a commercial turbine developed by KLIUX energies company was tested. The turbine has 8 twisted blades. The diameter and height are 40 cm and 50 cm, respectively. In order to analyse the wake, smoke visualization and numerical simulations were carried out. The analysis shows different structures generated by the rotation of the blades, the wake separation between the axis and the blades and the introduction of smoke into the axis wake. The 2D unsteady numerical simulations were performed. The domain of the grid is separated in two zones to control the number of nodes in the mesh: rotating mesh (1,600,000 nodes) and fixed mesh (50,000 nodes). The computational fluid dynamics (CFD) results are compared with the experimental flow visualization.
