RISTwo Tandem Cylinders With Passive Turbulence Control in Flow-Induced Vibration: Relation of Oscillation Patterns to Frequency Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow-induced vibrations (FIV) are conventionally destructive and should be suppressed. Since 2006, the Marine Renewable Energy Laboratory (MRELab) of the University of Michigan has been studying FIV of multiple cylinders ...
Nonlinear Piecewise Restoring Force in Hydrokinetic Power Conversion Using Flow-Induced Vibrations of Two Tandem Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow-induced vibrations (FIVs) of two tandem, rigid, circular cylinders with piecewise continuous restoring force are investigated for Reynolds number 24,000 ≤ Re ≤ 120,000 with damping, and restoring force function as ...
Synergistic Flow-Induced Oscillation of Multiple Cylinders in Harvesting Marine Hydrokinetic Energy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow-induced oscillations/vibrations (FIO/V) of cylinders in tandem can be enhanced by proper in-flow spacing to increase hydrokinetic energy harnessing. In a farm of multiple cylinders in tandem, the effect of interference ...
Interference Effects on Flow-Induced Oscillation of Three Tandem Cylinders With Passive Turbulence Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristics of flow-induced oscillation (FIO) of multiple tandem cylinders with passive turbulence control (PTC) change due to interference between PTC cylinders. Identifying positive and negative interferences is ...
Hydrokinetic Energy Conversion by Flow-Induced Oscillation of Two Tandem Cylinders of Different Stiffness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vortex-induced vibration for aquatic clean energy (VIVACE) converter harnesses hydrokinetic energy by enhancing flow-induced oscillations (FIOs) of elastically supported rigid cylinders in a river, tide, or ocean ...
The Simulation of Liquid Flow in the Pore Network Model of Nanoporous Media
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fluid–solid interaction force shows significant influence on liquid flow at nanoscale. Vast experimental observations in recent literatures have shown that Darcy's law cannot be applied to nanoporous media. In this ...
Virtual Spring–Damping System for Flow Induced Motion Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flowinduced motion (FIM) experiments of a single circular cylinder or multiple cylinders in an array involve several configuration and hydrodynamic parameters, such as diameter, mass, damping, stiffness, spacing, Reynolds ...
Computational and Experimental Assessment of Turbulence Stimulation on Flow Induced Motion of a Circular Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vortexinduced vibrations (VIVs) are highly nonlinear and it is hard to approach the problem analytically or computationally. Experimental investigation is therefore essential to address the problem and reveal some physical ...
Flow-Induced Vibration and Hydrokinetic Power Conversion of Two Staggered Rough Cylinders for 2.5 × 104 < Re < 1.2 × 105
Publisher: The American Society of Mechanical Engineers (ASME)
Interactive Flow-Induced Vibrations of Two Staggered, Low Mass-Ratio Cylinders in the TrSL3 Flow Regime
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow-induced vibrations (FIVs) of two elastically mounted circular cylinders in staggered arrangement were experimentally investigated. The Reynolds number range for all experiments (2.5 × 104 < Re < 1.2 × 105) was in the ...
