Since the energy demand increases, sources of fluid such as wind and marine have attracted widespread attention, especially vortex-induced vibrations (VIV) excited by energy. This paper proposes a harvesting device-based VIV concept. The proposed device converts mechanical oscillator into electrical Different design shapes, that motivates disturbance in airflow, were tested. designs numerically...

Abstract Introduction Valve-in-Valve transcatheter aortic valve implantation (ViV-TAVI) is an appealing treatment option for patients with degenerated bioprosthetic valves. However, high post-procedural transprosthetic gradients are very common after ViV-TAVI than TAVI native-valve stenosis. Aim We sought to evaluate (ΔP) and hemodynamic outcome in undergoing according type balloon post-dilatio...

Data structures defined as term algebras and programs built from recursive definitions complement each other. Computing in such surroundings guides us into Nriting simple programs Nith a clear semantics and performing a rigorous cost analysis on appropriate data structures. In this paper, we present a programming language so perceived, investigate some basic principles of cost analysis through ...

We study the structure of linear codes over the ring Bk which is defined by Fpr [v1, v2, . . . , vk]/〈v 2 i = vi, viv j = v jvi〉 k i, j=1. In order to study the codes, we begin with studying the structure of the ring Bk via a Gray map which also induces a relation between codes over Bk and codes over Fpr . We consider Euclidean and Hermitian self-dual codes, MacWilliams relations, as well as Si...

Transverse vortex-induced vibration (VIV) of a two-dimensional, elliptic cylinder with various aspect ratios and stiffness is studied. The elastically mounted heated, the flow direction aligned thermal-induced buoyancy force. transverse VIV can be suppressed as thermal control parameter, Richardson number (Ri), increases. Complete suppression achieved when Ri above critical value, Ric. increase...

Vortex-induced vibrations (VIV) of a cylinder in Newtonian fluid is model problem fluid–structure interactions and has been studied extensively. In this work, we study the influence shear-thinning shear-thickening fluids on VIV response one-degree-of-freedom flexibly-mounted cylinder. We consider system with mass ratio $m^*=2$ zero structural damping power-law at $Re_0 = 15$ 200$ , respectively...

With the extensive construction of ultra-high voltage (UHV) transmission lines, fatigue damage steel tube members caused by vortex-induced vibration (VIV) in tubular towers has received growing attention. Although some progress been made research VIV tubes uniform flow, there is still relatively scarce on at various inflow conditions. In this paper, a series wind tunnel tests are conducted to i...

Vortex induced vibrations (VIV) of a circular cylinder have been investigated experimentally using cyberphysical apparatus with m∗ = 8, ζ 0.005, and Re 4000. This study considers the application proper orthogonal decomposition (POD) spectral POD (SPOD) analysis to wake dynamics low-mass-ratio VIV in lower branch at U∗ 7.5. SPOD has previously shown better separate frequency-centered modal dynam...
