A recently developed numerical method for flows with moving boundaries is used for simulating the flow-induced vibration of cylinders. The key feature of the numerical method is that it allows us to simulate flows with moving boundaries on stationary Cartesian grids. The key features of the method are described. The method is used to simulate (a) transverse flow-induced vibration of a cylinder ...

Vibration of one hand reduces blood flow in the exposed hand and in the contralateral hand not exposed to vibration, but the mechanisms involved are not understood. This study investigated whether vibration-induced reductions in finger blood flow are associated with vibrotactile perception thresholds mediated by the Pacinian channel and considered sex differences in both vibration thresholds an...

In this paper, we conducted a selective review on the recent progress in physics insight and modeling of flexible cylinder flow-induced vibrations (FIVs). FIVs circular cylinders include vortex-induced (VIVs) wake-induced (WIVs), they have been center fluid-structure interaction (FSI) research past several decades due to rich engineering significance. First, summarized new understanding structu...

In this work, analytical solutions are provided to the nonlinear equations arising in thermal and flow-induced vibration in fluid-conveying structures using Galerkin-differential transformation method with cosine aftertreatment technique. From the analysis, it was established that increase of the length and aspect ratio of the fluid-conveying structures result in decrease the nonlinear vibratio...
