High-frequency self-excited oscillations in a collapsible-channel flow
High-Reynolds-number asymptotics and numerical simulations are used to describe twodimensional, unsteady, pressure-driven flow in a finite-length channel, one wall of which contains a section of membrane under longitudinal tension. Asymptotic predictions of stability boundaries for small-amplitude, high-frequency, self-excited oscillations are derived in the limit of large membrane tension. The...

15 صفحه اولInfluence of Nanoparticles Phenomena on the Peristaltic Flow of Pseudoplastic Fluid in an Inclined Asymmetric Channel with Different Wave Forms
The influence of nanofluid with different wave forms in the presence of inclined asymmetric channel on peristaltic transport of a pseudoplastic fluid is examined. The governing equations for two dimensional and two directional flows of a pseudoplastic fluid along with nanofluid are modeled and then simplified under the assumptions of long wavelength and low Reynolds number approximation. The ex...
متن کاملStreamwise localization of traveling wave solutions in channel flow.
Channel flow of an incompressible fluid at Reynolds numbers above 2400 possesses a number of different spatially localized solutions that approach laminar flow far upstream and downstream. We use one such relative time-periodic solution, which corresponds to a spatially localized version of a Tollmien-Schlichting wave, to illustrate how the upstream and downstream asymptotics can be computed an...
متن کاملShort-wave infrared excited SERS.
Optimisation of colloidal properties allows Surface Enhanced Raman Scattering (SERS) to be recorded from a range of analytes at 1546 nm, demonstrating the potential of SERS for use in a wavelength region of particular value for applications such as homeland security.
