Pushing Measurement to the Ultimate Stochastic Limit: the Stochastic Dynamics of Fluid-coupled Nanocantilevers Afosr Fa9550-07-1-0222 Final Report
We have developed a fundamental understanding of nanoscale fluid dynamics for fluidbased technologies with unprecedented capabilities. Using analytics and numerics we have investigated the Brownian driven, and externally driven, dynamics of micro and nanoscale elastic objects (such as cantilevers and beams) in a viscous fluid over a wide range of system parameters and for a number of experiment...
متن کاملThe stochastic dynamics of micron and nanoscale elastic cantilevers in fluid: fluctuations from dissipation
The stochastic dynamics of micron and nanoscale cantilevers immersed in a viscous fluid are quantified. Analytical results are presented for long slender cantilevers driven by Brownian noise. The spectral density of the noise force is not assumed to be white and the frequency dependence of the noise force is determined from the fluctuation-dissipation theorem. The analytical results are shown t...
متن کاملPull-in behavior analysis of vibrating functionally graded micro-cantilevers under suddenly DC voltage
The present research attempts to explain dynamic pull-in instability of functionally graded micro-cantilevers actuated by step DC voltage while the fringing-field effect is taken into account in the vibrational equation of motion. By employing modern asymptotic approach namely Homotopy Perturbation Method with an auxiliary term, high-order frequency-amplitude relation is obtained, then the infl...
متن کاملStochastic dynamics of nanoscale mechanical oscillators immersed in a viscous fluid.
The stochastic response of nanoscale oscillators of arbitrary geometry immersed in a viscous fluid is studied. Using the fluctuation-dissipation theorem, it is shown that deterministic calculations of the governing fluid and solid equations can be used in a straightforward manner to directly calculate the stochastic response that would be measured in experiment. We use this approach to investig...
متن کاملVariable Thermal Conductivity and Thermal Radiation Effect on the Motion of a Micro Polar Fluid over an Upper Surface
The intent of this analysis is to explore the influence of thermal radiation paired with variable thermal conductivity on MHD micropolar fluid flow over an upper surface. The novelty of the present model is to consider the fluid flow along an upper horizontal surface of a paraboloid of revolution (uhspr) with the porous medium. This physical phenomenon is described by a set of coupled...
