Purely elastic flow instabilities in microscale cross-slot devices.

Soft matter

Sousa PC, Pinho FT, Oliveira MS, Alves MA.
PMID: 26395149
Soft Matter. 2015 Dec 07;11(45):8856-62. doi: 10.1039/c5sm01298h.

We present an experimental investigation of viscoelastic fluid flow in a cross-slot microgeometry under low Reynolds number flow conditions. By using several viscoelastic fluids, we investigate the effects of the microchannel bounding walls and the polymer solution concentration on...

Characterization of the stochastic time evolution of short-term average intercore crosstalk in multicore fibers with multiple interfering cores.

Optics express

Alves TMF, Cartaxo AVT.
PMID: 29475309
Opt Express. 2018 Feb 19;26(4):4605-4620. doi: 10.1364/OE.26.004605.

A theoretical model for the stochastic time evolution of the intercore crosstalk (ICXT) in homogeneous weakly-coupled multicore fibers (MCF) with multiple interfering cores is proposed and validated experimentally. The model relies on the introduction of non-stationary time varying random...
