Kinetic theories have been developed to describe the hydrodynamics of polydisperse granular flows under different theoretical assumptions. In this study, six species theories are assessed using the DEM data obtained from simple shear flow containing bidisperse particles with low and moderate solid vol-ume fraction (Galvin, 2007). It was shown that ...

The hydrogen embrittlement micromechanisms and the effect of carbon interstitial on hydrogen distribution were characterized in Fe40Mn40Ni10Cr10 and Fe38Mn41Ni10Cr10C1 medium entropy alloy. Ex-situ microstructural observations revealed that the segregation of carbon on grain boundaries suppresses hydrogen from being trapped in the grain boundaries ...
Polydisperse particles are ubiquitous, yet their unique roles are inadequately understood. In this study, CFD-DEM study on the fluidization of polydisperse particles in bubbling micro-fluidized beds was performed. The method was firstly validated by the experimentally measured bed expansion characteristics and voidage of emulsion phase. Detailed an...

The tensile creep performance of a polycrystalline Co/Ni-base superalloy with a multimodal γ distribution has been examined at 800◦C and 300 MPa. The rupture life of the alloy is comparable to that of RR1000 tested under similar conditions. Microstructural examination of the alloy after testing revealed the presence of continuous γ precipitates and...
The multigrain model (MGM) is the most widely used single-particle model, giving a detailed description of phenomena during olefin polymerization. However, the detailed modeling of the diffusion-reaction process inside the catalyst particles requires solving a large number of ordinary differential equations, which is unsuitable for coupling with mu...

Inside a spacecraft, the temperature and humidity, suitable for the human crew onboard, also creates an ideal breeding environment for the proliferation of bacteria and fungi; this can present a hazard to human health and create issues for the safe running of equipment. To address this issue, wear-resistant antimicrobial thin films prepared by magn...
When applied to catalysis and related materials phenomena, grain boundary (GB) engineering optimizes over many currently disparately defined properties. Such properties include GB mobility, solute diffusivity, and catalytic footprints correlating current density with dislocation-induced strain. A recent universalizing framework has systematically c...
