Fluid-structure feedback in complex flow environments
Fluid-structure-feedback plays an important role in many engineering applications and natural phenomena. Specifically, the structure movements or deformation can highly alter the local flow and leads to complex coupling between wake flows and structure dynamics. In this talk, I will discuss three interesting examples of fluid-structure-feedback with the combination of experimental measurements and theoretical frameworks. First, I will talk about the deformation and oscillation of flexible wall-mounted plates under various flow environments, which mimics the dynamics of grass in both air and water flows. The second topic will be the boundary layer flow over obstacles and the induced sediment motions; special attentions will focus on the coupling between wake characteristics and sediment suspension. Last, I will talk about the control and optimization of wind turbine operations with wind tunnel experiments.
