ABSTRACT

The interest in studying wind mills is that they are in the renewable energies context which had gained a great importance nowadays regarding to the world demand for energy that by 2050, could double or even triple as the global population grows [1]. In this background, this paper represents a numerical investigation on a new vertical axis wind turbine (VAWT) (Darrieus type). The idea proposed was to have more blades on each side of the original blades and to examine how such a configuration would affect the machine’s performance. The proposed H-rotor defined as a three tandem straight-bladed turbine (Tandem turbine) is numerically tested. The validation of the numerical code was made through the comparison of numerical simulations with experimental study of a two-bladed VAWT performed by [2]. The study concerns a vertical axis wind turbine with two NACA0018 blades. The turbulence model for calculations is the Spalart-Allmaras model. The comparison of aerodynamic coefficients leads to a rather satisfactory agreement with literature. Such results encourages us to undertake more advanced work.
