| description | Recently, there has been a resurgence of interest in vertical axis wind
turbines (VAWT) due to its advantages over the conventional horizontal axis
wind turbines. More experimental and numerical simulations is needed for the
understanding of VAWT operations, and the performance for different blade
design and turbine configurations needs to be investigated to develop more
efficient VAWT designs.
In this project, a small scale VAWT was designed and built in which the
blade design and configuration could be modified easily for testing.
Performance characteristics with SD8020, NACA0022 and S1223 airfoils at
different turbine configuration were also analyzed. Finally, a basic flow
simulation was performed which illustrated the blockage effect of wind tunnel
testing.
Experimental test showed that NACA0022 blades which are symmetric and
thick gave the best P C performance while the asymmetric S1223 blades also
showed promising results when placed in the right configuration. It was also
deduced that 4-blade configuration has a better self-starting performance
than a 3-blade configuration due to its higher solidity. The CFD simulations
suggested that the P C values could be augmented in a wind tunnel test. |
