Cost-Effectiveness of Valve-in-Valve Transcatheter Mitral Valve Replacement Versus Redo Surgical Mitral Valve Replacement for Degenerated Bioprosthetic Mitral Valve [PDF]

Structural Heart
Background: Degenerated bioprosthetic mitral valves (MVs) are associated with significant morbidity and health care expenditures. For certain patients, valve-in-valve transcatheter MV replacement (ViV TMVR) has emerged as a promising treatment option due

Application of nonlinear stiffness mechanism on energy harvesting from vortex-induced vibrations

Frontiers in Marine Science, 2023
This study investigates the potential of vortex-induced vibration (VIV) as a renewable energy source, achieved when fluid flow interacts with a bluff body, inducing self-sustained oscillations through vortex shedding in the wake.

Experimental Study on Vibration of a Rotating Pipe in Still Water and in Flow

Polish Maritime Research, 2023
To illustrate the vibration characteristics of a rotating pipe in flow, experiments were conducted for a pipe in flow, a rotating pipe in still water and a rotating pipe in flow. For the pipe in flow without rotation, the trajectory diagram is ‘8’ shaped.

Vortex-Induced Vibration Characteristics of a PTC Cylinder with a Free Surface Effect

Energies, 2020
The experimental study of vortex induced vibration needs to be carried out in water tunnel, but in previous associated simulation work, the water tunnel was treated as an infinite flow field in the depth direction with the effect of the free surface ...
