Wind tunnel test on the effect of solidity on the wake evolution characteristics of twin counter rotating vertical axis turbines

The wake of a vertical axis turbine is a type of unsteady flow with multi-scale coherent structures formed by a series of complex spatiotemporal evolutions of blade vortex shedding. The evolution characteristics and interaction of multi-scale coherent structures between two turbine wakes are the bas...
