[会议背景介绍]

Progress in understanding turbulence and flow control is enabling scientists to improve aerodynamic / hydrodynamic performance by reducing drag, increasing lift or thrust and reducing noise under critical conditions that may result in massive separation, strong vortical dynamics, amplification of harmful instabilities (flutter, buffet), and flow -induced vibrations. Theory together with large-scale simulations and experiments have shown new features of turbulent flow in the boundary layer over wings, and in thin shear layers immediately downstream separation. Spontaneous and artificially generated fluctuations can be used to affect the turbulent flow, leading to reduction of noise and drag. Electromechanical actuation and energy conversion can be achieved efficiently using a variety of mechanisms available from a range of novel smart actuators to effect morphing.The symposium will investigate a combination of new insights into turbulent flow interacting with actively deformable structures, leading to new ways of adapting and controlling the body shape and vibrations, to respond to these critical conditions. Furthermore, the symposium topics will include “smart”, bio-inspired methods together with new dynamically controlled aerodynamic and hydrodynamic shapes in order to attenuate the harmful effects and to increase performance and safety. Progress in these areas is receiving a great deal of impetus from international research groups, especially stimulated by major contracts related to this topic, involving key multinational industrial companies particularly in aeronautics and naval architecture, stimulated by targeted government programs. This symposium aims at bringing together the leading international groups of researchers working in the scientific communities.The symposium will include advanced theoretical approaches experimental and simulation methods showing in synergy how smart designs lead to considerable benefits compared to conventional ways. The symposium is expected to draw the scientific advances in the state of the art and will establish important outlooks of research concerning these topics.
