Viscous Fluid Flow-Induced Nonlocal Nonlinear Vibration of Embedded DWBNNTs
In this article, electro-thermo nonlocal nonlinear vibration and instability of viscous-fluid-conveying double–walled boron nitride nanotubes (DWBNNTs) embedded on Pasternak foundation are investigated. The DWBNNT is simulated as a Timoshenko beam (TB) which includes rotary inertia and transverse shear deformation in the formulation. Considering electro-mechanical coupling, the nonlinear govern...
متن کاملElectromagnetic energy harvesting from flow induced vibration
A new electromagnetic energy harvester for harnessing energy from flow induced vibration is developed. It converts flow energy into electrical energy by fluid flow and electromagnetic induction. A finite element model for estimation of the generated voltage of the energy harvester is developed. A prototype of the energy harvester is fabricated and tested. Experimental results show that an outpu...
متن کاملUniversal Dynamics in Flow-Induced Cable Vibration
A combined analytical-experimental approach is used. Analytical aspects focus on the continued development of a low-order model that utilizes a series of diffusively coupled circle map oscillators along the cylinder span. This coupled map lattice has been extended to include control logic to develop a very efficient low order model for control studies in cylinder wake flows. On the experimental...
متن کاملAnalyzing Random Vibration Fatigue
Determining the fatigue life of parts under periodic, sinusoidal vibration is a fairly straightforward process in which damage content is calculated by multiplying the stress amplitude of each cycle from harmonic analysis with the number of cycles that the parts experience in the field. The computation is relatively simple because the absolute value of the vibration is highly predictable at any...
متن کاملMasters Thesis: Flow Induced Vibration Harvest
This thesis studies ways of broadening the range of a piezoelectric flow induced vibration harvester. The proposed device consists of a flap connected with a hinge to a spring. Existing harvesters are designed to replace or charge batteries for low power systems in the range of milliwatts. These systems produce low amounts of power, but for low flow speeds. The objective of this thesis is to in...
