Guided Waves in a Solid Rod Embedded in Infinite Medium with Weak Interface

MATEC Web of Conferences, 2016
The dispersion relation of the infinite long rod model with a weak interface has been deduced via wave equation of the guided waves and boundary spring interface model.

Effects of Temperature and Axial Strain on Four-Wave Mixing Parametric Frequencies in Microstructured Optical Fibers Pumped in the Normal Dispersion Regime

Photonics, 2014
A study of the effect of temperature and axial strain on the parametric wavelengths produced by four-wave mixing in microstructured optical fibers is presented. Degenerate four-wave mixing was generated in the fibers by pumping at normal dispersion, near

Axial dispersion via shear-enhanced diffusion in colloidal suspensions [PDF]

, 2012
The familiar example of Taylor dispersion of molecular solutes is extended to describe colloidal suspensions, where the fluctuations that contribute to dispersion arise from hydrodynamic interactions. The generic scheme is illustrated for a suspension of

Gas Holdup and Liquid-Phase Dispersion in Packed Bubble Columns

Tikrit Journal of Engineering Sciences, 2013
The gas holdup and liquid phase axial dispersion coefficient are measured in two semi batch packed bubble columns, 10 and 15 cm diameter for an air–water system, at atmospheric conditions.

Mixing and axial dispersion in Taylor–Couette flows: the effect of the flow regime [PDF]

, 2016
The paper focuses on mixing properties of different Taylor–Couette flow regimes and their consequence on axial dispersion of a passive tracer. A joint approach, relying both on targeted experiments and numerical simulations, has been used to investigate ...

Axial Dispersion and Back-mixing of Gas Phase in Pebble Bed Reactor

Tikrit Journal of Engineering Sciences, 2013
Despite the worldwide attended of pebble bed reactors (PBRs), there is a lack of fundamental understanding of the complex flow pattern. In this work, the non-ideal flow behavior of the gas phase which is used for cooling has been investigated ...
