| Outline of Final Research Achievements |
Our study aims to improve the performance of cross-flow wind turbine by using two flow deflectors(FDs) as wind collector that improve the ambient wind environment of the wind turbine.
In this study, to investigate the influence of upscaling of the wind turbine with FDs, three types of wind turbine models were examined, one was the base model with 114 mm diameter and 12 blades and the other two were upscaled 1.5 times in diameter. Each upscaled model has different blade airfoil size and the number of blades. One upscaled model was similarly upscaled and the other had 19 blades the airfoil size of which was same as that of base model. The influence of difference in upscaling of the wind turbine with FDs on the performance and flow field was considered through the results of performance test and 2D numerical analysis.
As a result, with FDs, the upscaling method to keep the blade airfoil size smaller than the size of FDs was better to get high performance improvement effect of FDs.
