Abstract:
... The efficiency of a vertical axis wind turbine (VAWT) can be improved by placing a shield or deflector upstream of the turbine to reduce the negative torque on the blade. However, previous studies mainly focused on fixed shields or deflectors, and the performance of the VAWT was significantly affected by the wind direction. Considering this, this paper proposed a novel passive-pitch shield (PPS) w ...

Abstract:
... Wake redirection is a wind farm control strategy that aims at increasing the overall power yield of a wind farm. It involves intentional misalignment of the rotors of upstream wind turbines with respect to the wind direction, thereby diverting their wakes aside from downstream turbines. The yaw misalignment angles are typically optimized using static wake models. In real-life, due to the rapid flu ...

Here this new type of major event so-called the delayed super El Niño is realistically captured by a simple dynamical model for the equatorial Pacific with emphasis on the role of state-dependent stochastic wind bursts. We analyze qualitative analogues for this event co ...

A higher wind velocity does not represent a better performance, which depends on wind angle (α), which is the angle between wind direction and outward normal of the wall with the window. A windward situation (0°≤α < 90°) is suggested, where the scenario with α = 0 shows the best performance. It is surpr ...

Partly due to the lack of long-term PBL observations during the winter in Beijing, the complex relationships between the large-scale synoptic patterns, local PBL structures/processes, and PM2.5 pollution have not been fully understood. Thus, this study sy ...
