In this paper, the effects of carbon nanotube (CNT) orientation and aggregation on the static behavior of functionally graded nanocomposite cylinders reinforced by CNTs are investigated based on a mesh-free method. The used nanocomposites are made of the straight CNTs that are embedded in an isotropic polymer as matrix. The straight CNTs are oriented, randomly or aligned or local aggregated int...

In this paper, we study the stationary incompressible power law fluid flow in a thin porous medium. The media under consideration is bounded perforated 3D domain confined between two parallel plates, where distance plates very small. perforation consists an array solid cylinders, which connect perpendicular direction, distributed periodically with diameters of small size compared to period. For...

This paper calculates and analyzes the collision freezing characteristics of water droplets on cylindrical conductors with different diameters deduces variation law icing weight change rate rotating wind speed, ambient temperature, liquid content, median volume diameter. Then, a prediction value-seeking method environment parameters based circular is determined. The laboratory test results show...

Bound states in the continuum (BICs) a periodic structure sandwiched between two homogeneous media have interesting properties and useful applications photonics. The topological nature of BICs was previously revealed based on charge related to far-field polarization vector surrounding resonant states. Recently, it established that when symmetry-protected (with nonzero charge) are destroyed by g...

By means of a photoelastic method, we access the visualization of acoustic waves propagating in a one-dimensional array of noncohesive cylinders. As pointed by Nesterenko in the case of spherical grains [V. F. Nesterenko, J. Appl. Mech. Tech. Phys. 24, p. 567 (1983)], the nonlinearity of the contact law between the grains induces a dependence of the wave velocity both on its amplitude and on th...

The scattering of water waves by a long array of rigid vertical circular cylinders is analysed under the usual assumptions of linear theory. Our primary goal is to show how solutions obtained for semi-infinite arrays can be combined to provide accurate and numerically efficient solutions to problems involving long, but finite, arrays. The particular diffraction problem considered here has been ...

We present a multisource, multidetector phased-array approach to diffuse optical imaging that is based on postprocessing continuous-wave data. We previously showed that this approach enhances the spatial resolution of diffuse optical imaging. We now demonstrate the depth discrimination capabilities of this approach and its potential to perform tomographic sectioning of turbid media. The depth d...
