Abstract

In the present study, the blade shape of a new kind of VAWT that has a different structure in comparison with other drag-based wind turbines, hunter turbine, is investigated and then optimized. The purpose of this study is designing a blade with the greatest drag coefficient in order to increase the power coefficient of the turbine. In this study 4 kinds of flat blades, including squared, circular, semi-circular and compound flat plates, have been investigated in static state experimentally and numerically. The numerically simulation has been carried out by assuming the incompressible, unsteady two-dimensional and steady three-dimensional flow. Flow simulation has been accomplished by discretizing and solving the Navier-Stokes equations with shear-stress transport (SST) k-ω turbulence model. This model simulates the near-wall flow by directly solving Navier-Stokes equations. In experimental method, the drag force is measured by a load-cell and the drag coefficient has been calculated by using the blade area. The results show a great agreement between the experimental and numerical data. It is concluded that the squared blade has the greatest drag coefficient among the considered cases, which is 1.18.
