| description | Modern wind turbines are categorized as horizontal axis wind turbines (HAWTs) and
vertical axis wind turbines (VAWTs), which are currently being utilized for diversified
applications. The basic theoretical advantages of VAWTs are: (i) they accept the wind from
any direction, and (ii) the generator, gearbox etc. can be placed on the ground. Selection of
airfoil is one of the most critical factor in achieving optimum aerodynamic performance and
in determining the optimum dimensions of a fixed-pitch straight-bladed vertical axis wind
turbine (SB-VAWT). Airfoil related design changes also have the potential for increasing the
cost effectiveness of VAWTs. Most of the earlier research works carried out by different
research organizations mainly used NACA symmetric airfoils which were unable to self-start
properly. In this paper, detail systematic investigative analyses have been performed with
high-lift asymmetric airfoils appropriate for self-starting and better performance of smaller
capacity SB-VAWT. In order to do the performance analysis, a computational scheme has
been developed using the Cascade Model and XFOIL, a sub-sonic airfoil design and analysis
tool developed in MIT. It has been found out that the results obtained from the
computational scheme conform reasonably well with the experimental results. Subsequently,
three prospective airfoils have been identified using this computational scheme. It has been
found that their performance is better than conventionally used NACA 0015 at low tip speed
ratio range where the problem of self-starting happens. |
