振荡绕流的概况和发展

The Development of Oscillatory Flow Around Bluff Bodies

近十多年来,在海洋工程发展的推动下,水力学和流体力学再度结合,以波浪和旋涡为特征的水动力学得到了迅猛的发展,振荡绕流问题是这一领域中的关键问题之一。 本文对振荡绕流研究的历史、应用背景和研究概况作扼要介绍。在这基础上给出它的发展方向和前沿课题,供有关研究参考。

Since the 1970's due to the requirement of the ocean engineering, the hydromechanics and the f luidmechanics has been merged together, and the hydrodynamics characterized by waves and vortices has experienced rapid development. In this field problems of the oscillatory flow around bluff bodies play an very important role.In this paper a brief survey of the history, the background, and the recent development of the oscillatory flow research is presented. The trend of developments and the outstanding problems were proposed.
