Driven low density granular mixtures.
We study the steady state properties of a two-dimensional granular mixture in the presence of energy driving by employing simple analytical estimates and direct simulation Monte Carlo. We adopt two different driving mechanisms, (a) a homogeneous heat bath with friction and (b) a vibrating boundary (thermal or harmonic) in the presence of gravity. The main findings are the appearance of two diff...
متن کاملIntegration Technologies for Silicon Carbide-BasedCeramics for Micro-Electro-Mechanical Systems-LeanDirect Injector Fuel Injector Applications
Advanced joining approaches are critically needed for the fabrication and integration of silicon carbide-based micro-electro-mechanical systems lean direct fuel injectors for jet engines. Diffusion bonding of silicon carbide with titanium interlayers offers advantages such as uniform application/surface coverage and no flow of the interlayer or the reaction formed phases during joint processing...
متن کاملMicro-assembly Technologies
In micro-manufacture manual assembly often becomes unfeasible due to the small size of the products. As a result microassembly is becoming a sector of strategic importance in high labour cost areas due to the specific needs of automated fabrication and assembly processes. This in turn makes outsourcing a less attractive option. It is well recognised that the production of miniaturised products ...
متن کاملOrdering phenomena in cooling granular mixtures.
We report two phenomena, induced by dynamical correlations, that occur during the free cooling of a two-dimensional mixture of inelastic hard disks. First, we show that, due to the onset of velocity correlations, the ratio of the kinetic energies associated with the two species changes from the value corresponding to the homogeneous cooling state to a value approximately given by the mass ratio...
متن کاملPossible Stratification Mechanism in Granular Mixtures
We propose a mechanism to explain what occurs when a mixture of grains of different sizes and different shapes (i.e., different repose angles) is poured into a quasi-two-dimensional cell. Specifically, we develop a model that displays spontaneous stratification of the large and small grains in alternating layers. We find that the key requirement for stratification is a difference in the repose ...
