The behavior of wind turbines wakes is of considerable interest, especially in the context of wind farms where wake-turbine interactions are important. Here we investigate …
The variety of configurations for vertical-axis wind turbines (VAWTs) make the development of universal scaling relationships for even basic performance parameters difficult. Rotor …
Cross-flow turbines harness kinetic energy in wind or moving water. Due to their unsteady fluid dynamics, it can be difficult to predict the interplay between aspects of rotor geometry …

In this article, the suitability of the Reynolds-averaged Navier–Stokes (RANS) to predict the dynamic response in the startup process of small-scale Darrieus vertical-axis wind turbines …
This paper presents the dynamic behavior of a fluidic diode (FD) subjected to periodic flow (oscillatory flow). This study captures the transient performance of the FD, which a steady …
