STUDY OF DYNAMIC STRESSES IN PIPE NETWORKS AND PRESSURE VESSELS USING FLUID-SOLID-INTERACTION MODELS

摘要

A lack of understanding of the fluid-structure interactions has resulted in a number of infamous structural failures in the past. For example, the collapses of the Tay Bridge in Scotland in 1879, the Tacoma Bridge in 1948 and three tall cooling towers in Ferrybridge/England in 1965 have been intrinsically related to fluid forces acting on the structure. Flutter, flow-induced vibration, divergence and related phenomena may be studied using the Fluid-Solid-Interaction (FSI) approach. This paper gives three examples of the FSI approach and shows the innovative application of state-of-the-art computational methods toimprove realism and accuracy in engineering analyses.
