Flow-induced periodic snap-through dynamics
WebJan 5, 2024 · Numerical simulations of evolution characteristics of slug flow across a 90° pipe bend have been carried out to study the fluid—structure interaction response induced by internal slug flow. The two-phase flow patterns and turbulence were modelled by using the volume of fluid (VOF) model and the Realizable k−ε turbulence model respectively. … WebOct 15, 2024 · The time-domain voltage response in Fig. 13 (e) shows the periodic snap-through motion with relatively high frequency vibrations at each snap-through phenomenon, which is not observed from the velocity response of the tip mass in Fig. 11 (e). This indicates that the sub-beams of the harvester undergo more complicated local …

WebAug 3, 2024 · Flow-induced vibration (FIV) is a phenomenon in which the flow passing through a structure exerts periodic forces on the structure. Most studies on FIVs focus on suppressing this phenomenon. However, the Marine Renewable Energy Laboratory (MRELab) at the University of Michigan, USA, has developed a technology called the … WebSep 2, 1998 · A rarefied gas in a channel of two parallel plane walls with a spatially periodic steady temperature distribution, on which a series of ditches is dug periodically, is considered, and the behavior of a flow induced by the temperature variation on the walls is investigated numerically for various Knudsen numbers and ditch sizes by the standard …
WebDec 16, 2024 · This study is an effort to encapsulate the fundamentals and major findings in the area of fluid-solid interaction, particularly the flow-induced vibrations (FIV). Periodic flow separation and vortex shedding stretching downstream induce dynamic fluid forces on the bluff body and results in oscillatory motion of the body.
