Vortex-induced vibration (VIV) of bluff bodies is one type flow-induced phenomenon, and the possibility using it to harvest hydrokinetic energy from marine currents has recently been revealed. To develop an optimal harvester, various parameters such as mass ratio, structural stiffness, inflow velocity need be explored, resulting in a large number test cases. This study primarily aims examine va...

The Cover Feature shows the photocatalytic hydrogen production by dual Ru(II)-dye sensitized layered niobate oxide with intercalated Pt cocatalyst in presence of redox-reversible M-substituted polyoxometalate anions (M-POM, M = VIV, MnII). In their Research Article, A. Kobayashi and co-workers found that activity is remarkably higher MnII-POM aq. than VIV-POM despite comparable redox potentials...

Abstract A parked wind turbine can be subjected to large yaw angles, which causes vortex shedding. Under some particular inflow conditions, the interaction between shed vorticity and blade structure could lead Vortex-Induced Vibrations (VIV). VIV are an instability where response grows until it reaches a limit cycle oscillation. In this paper, we will focus on last part of response. We see that...

Fluid–structure interactions of non-circular prisms are significance from a scientific and practical viewpoint. In this paper, we present new experimental observation flow-induced vibrations associated spectral characteristics transversely oscillating D-section prism at an angle attack ? varying 0° to 180°, where = 180° represent the configuration with upstream curved flat part, respectively.

For flow-induced vibration of a rounded-square cylinder under the effect proximity interference by stationary splitter plate downstream, numerical study is presented for various corner-radius R(0.1−0.5), reduced velocity U*(2−12.5), cylinder-plate gap G*(0.3,2.0), Reynolds number Re = 100, mass ratio M*=1, damping coefficient ζ=0.005, plate-length L*=1, and plate-thickness t*=0.05. R, vortex-in...

in the present paper the behavior of an elastically mounted cylinder in low and high mass-damping ratio is investigated. for high mass-damping ratio, a classical wake oscillator model is used. at the first, by neglecting all damping and nonlinear terms of this model, the possibility of using a linear model for determination of the lock-in range and the dominant mode is investigated. then, witho...

An 81-year-old man, who had undergone a complex cardiosurgical procedure 8 years previously (aortic valve replacement by Medtronic Hancock II 23 mm and mitral valve replacement by Medtronic Hancock II 31 mm, tricuspid valve repair using the Kay technique, and coronary artery bypass surgery with left internal mammary artery (LIMA) to left anterior descending (LAD)), was admitted to the hospital ...
