Uniform shock waves in disordered granular matter
(American Physical Society, 2012-10)
The confining pressure P is perhaps the most important parameter controlling the properties of granular matter. Strongly compressed granular media are, in many respects, simple solids in which elastic perturbations travel ...
Study of effectiveness factors with non-uniform catalyst distributions for methane steam reforming
(Springer Netherlands, 2020-07-14)
In the present work, three kinetic expressions for methane steam reforming with different methane and water partial pressures dependence were studied. Methane effectiveness factors were simulated for spherical uniform ...
Effect of high-pressure homogenization on different matrices of food supplements
There is a growing demand for food supplements containing high amounts of vitamins, phenolic compounds
and mineral content that provide health benefits. Those functional compounds have different solubility properties,
and ...
Aproximação para a seção transversal de absorção na transferência de calor por radiação em gases não-uniformes
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA MECÂNICA, 2021-02-23)
Accurate computations of radiative heat transfer in participating gases
require detailed knowledge of the spectral data of radiative properties. This can be
achieved either performing line-by-line calculations or using ...
Rotochemical heating in millisecond pulsars: modified Urca reactions with uniform Cooper pairing gaps
(2010)
Context: When a rotating neutron star loses angular momentum, the reduction in the centrifugal force makes it contract. This perturbs each fluid element, raising the local pressure and originating deviations from beta ...
Hydraulic characterization of turbulent flow drippersCaracterização hidráulica de gotejadores de fluxo turbulento
(2018-05-15)
In the evaluation of hydraulic performance of four models of not self-compensating drippers was used a bench of tests with capacity for 25 drippers of each model. Each model was subjected to different pressures (p), thus ...
Metallic behavior in STO/LAO heterostructures with non-uniformly atomic interfaces
(2020-09-01)
The search for new and low-power switching devices involving the integration of semiconductor thin films is of interest, and has led to renewed research because such devices may exhibit innovative properties. Here, we ...
