| Outline of Final Research Achievements |
Wind power now speads at a pace of ten folds a decade, and experiences various problems which has not been pointed out before such as lack of power estimated, blade damage with sudden unstable airflows, and flow noises claimed by residents. All of them associate to pressure field of flow. Particle image velocimetry has been contributing to experimental fluid dynamics though, it hardly produces problem-solving of the issue above. This is because PIV does not measure pressure field directly despite to its rich information of velocity vector field. In this project, we have developed several numerical and experimental systems that can measure multi-dimensional pressure field as a function of time, to improve the pace of development in trial-and-error designs of various wind turbines.
