Fluid-Structure Interactions: Cross-Flow-Induced Instabilities

摘要

Flow-induced forces and vibrations on deformable objects abound in nature and man-made structures. A particularly important class of fluid-structure interaction problems involves crossflow-induced instabilities. Specifically, problems that presume a slender geometry such that the problem can be classified as flow normal to the long axis of the structure. Crossflow-induced vibrations appear in a wealth of practical engineering problems including, for example, transmission lines, arrays of cylinders in heat exchangers, tall buildings, bridges, and offshore structures, to mention only a few.
