TL;DR: In this paper, the authors studied the thermal-hydraulic performance of a sinusoidal-wavy wall mini-channel with wall phase shift and variable wavelength, and found that the shape of nanoparticles can greatly influence the performance of the mini channel.

TL;DR: In this paper, the effect of the coordination number and the fluctuation of the number of contacts per particle was investigated by means of numerical simulation, and it was shown that the results can be attributed to the coordination.
Abstract: Physical experiments on wave propagation on granular material control two macroscopic parameters that are assumed to characterize the response of a given assembly: the isotropic pressure p0 and the solid volume fraction . Here, by means of numerical simulation, we investigate the effect of the coordination number (the average number of contacts per particle) and the fluctuation of the number of contacts per particle Z'. We adopt a numerical protocol to create several initial packings characterized by the same volume fraction and, for a given isotropic pressure, we are able to obtain different coordination numbers. That is, pressure and coordination number, for a given volume fraction, are independent. The result is that packings with fixed volume fraction and isotropic pressure exhibit a different elastic response. We attribute this behavior only to the coordination number as we find, surprisingly, that is linked to Z'.

TL;DR: In this article, the strength of aluminum 6092/B 4 C p (boron carbide) metal-matrix composites fabricated by two different powder consolidation routes, extrusion and sintering/hot isostatic-pressing (HIPing), were made and tested over a wide range of strain rates (10 −4 to 10 4 ǫ s −1 ).
Abstract: Aluminum 6092/B 4 C p (boron carbide) metal-matrix composites (MMC) fabricated by two different powder consolidation routes, extrusion and sintering/hot isostatic-pressing (HIPing), were made and tested over a wide range of strain rates (10 −4 to 10 4 s −1 ). The strength of these MMCs increases with increasing volume fraction of particulate reinforcement. Strain hardening is observed to increase with increasing volume fraction of reinforcement at lower strains ( 5 μm) considered. Finally, the Li–Ramesh model captures the observed high-rate behavior exhibited by these powder-consolidated composites.
