There are a wide range of applications in which it is desirable to mitigate unsteady load fluctuations while preserving mean loading. This often achieved with active control systems, but passive systems sometimes more for enhancing reliability. the case, example, wind and tidal turbines, where loading limits fatigue life turbine results power peaks at generator. Here, we consider mitigation tha...

• Streamwise vortices are formed around the serration under loading; Vortices cause a local increase in wall-pressure fluctuations; Wall-pressure fluctuation increased by induced mean flow-turbulence interaction; Aerodynamic loading associated with loss of noise reduction performance serrations; The impact aerodynamic on serrated trailing edge is studied experimentally. and acoustic measurement...

Morphing trailing edge wing as an important morphing technology has gained wide attention because of its advantages, such gust mitigation, improved aerodynamic efficiency, and reduced radar reflective area. However, the key problems low load carrying capacity insufficient smooth deformation profile are still not solved in a balanced manner. The purpose this paper is to design seamless structure...

Climate change is expected to cause geographic shifts in tree species' ranges, but such shifts may not keep pace with climate changes because seed dispersal distances are often limited and competition-induced changes in community composition can be relatively slow. Disturbances may speed changes in community composition, but the interactions among climate change, disturbance and competitive int...
