Abstract
Wind energy is one of the most important renewable energies since it reduces environmental pollution. Darrieus VAWTs with straight-bladed are more prevalent in small-scale power generation due to their simple blade design and easy construction. The investigation of the performance of VAWTs is a topic that is fascinating for Researchers to look into. Researchers have paid special attention to the Double Multiple Stream Tube (DMST) model for VAWT simulation because of the good correlation between the DMST model and the experimental results. In this paper Double Multiple Stream Tube analysis using Matlab programing to predict the aerodynamic performance of H-type Darrieus fixed pitch VAWT, More specifically, the power coefficient (Cp) and the tip speed ratio (TSR). The fact that an H-type Darrieus rotor has poor self-starting despite having a good power coefficient which is a constant worry at low wind speeds. Selection of the airfoil is one of the most essential factors to take into account while trying to enhancement the aerodynamic performance of H-type Darrieus fixed pitch VAWT. In this study first, results from experiments were used for the validation of the model, and then, 4 different families of symmetrical airfoils compared. The results indicate that the symmetrical airfoil S-1046 showed exceptional aerodynamic performance and a high starting torque for a low wind speed of 4m/s.
