چکیده

A novel, digitally based geometrical packing algorithm, called DigiPac, is used in an investigation into the segregation of non-spherical particles, due to vibration or shaking. Comparison between simulations and experiments shows a consistent, albeit qualitative, correlation, supporting the hypothesis that segregation can be explained from a geometrical instead of mechanistic point of view, in terms of relative mobility between particles of different shapes and sizes. Thus, although the geometrical packing algorithm cannot be used to follow the dynamics of a segregation process, it provides a software tool for quick trend finding as to if and how likely segregation is to occur for any given mixture of arbitrary shapes. Such a tool is useful for process design and optimization of particulate solids.

Exact analytical approach for free longitudinal vibration of nanorods based on nonlocal elasticity theory from wave standpoint

In this paper, free longitudinal vibration of nanorods is investigated from the wave viewpoint. The Eringen’s nonlocal elasticity theory is used for nanorods modelling. Wave propagation in a medium has a similar formulation as vibrations and thus,  it can be used to describe the vibration behavior. Boundaries reflect the propagating waves after incident. Firstly, the governing quation of nanoro...

Ritz Method Application to Bending, Buckling and Vibration Analyses of Timoshenko Beams via Nonlocal Elasticity

Bending, buckling and vibration behaviors of nonlocal Timoshenko beams are investigated in this research using a variational approach. At first, the governing equations of the nonlocal Timoshenko beams are obtained, and then the weak form of these equations is outlined in this paper. The Ritz technique is selected to investigate the behavior of nonlocal beams with arbitrary boundary conditions ...

Multilaminate Elastoplastic Model for Granular Media

A multilaminate based model capable of predicting the behavior of granular material on the basis of sliding mechanisms and elastic behavior of particles is presented. The capability of the model to predict the behavior of sand under arbitrary stress paths is examined. The influences of rotation of the direction of principal stress axes and induced anisotropy are included in a rational way witho...

Predicting the Liquid Density of Gas Condensates and LNG Mixtures from Equations of State

In this contribution, two approaches are followed to predict the saturated liquid density of liquefied natural gas (LNG) mixtures. In one approach, 12 cubic equations of state (EoSs), comprising the popular Peng-Robinson (PR) and Redlich-Kwong-Soave (RKS), are employed to predict the saturated liquid density of 20 LNG mixtures. In the other approach, these EoS are used in conjunction with a rec...
