The application of an external magnetic field on a fluidized bed of ferromagnetic particles is well known in a conventional two-phase, gas–solid or liquid–solid fluidization. The external magnetic field significantly changes the fluidized bed fluid-dynamic behavior and if creatively used may enhance the bed performance. In this paper, a theoretical fluid-dynamic model describing behavior of a G...

The unexpected weakness of some faults has been attributed to the emergence of acoustic waves that promote failure by reducing the confining pressure through a mechanism known as acoustic fluidization, also proposed to explain earthquake remote triggering. Here we validate this mechanism via the numerical investigation of a granular fault model system. We find that the stick-slip dynamics is af...

The aerodynamic behavior of wet forestry biomass particles mechanically shaken in a fluidized bed was analyzed with turning velocity between 0.5 and 2 r.p.s. It was concluded that the agitation exerts an important effect on the fluidization of wet biomass particles. The effect of the agitator is not relevant if the particles have low humidity content. In addition, a methodology based on the Erg...

The processes of dehydration and granulation are associated with the heat transfer to solid particles from gas coolant, which acts as a fluidizing agent causes stochastic movement granular material in apparatus. To implement layered structure mechanism organic-mineral fertilizers it is necessary ensure intensive circulation gradual passage through appropriate technological zones main problem lo...

Fluidization of non-spherical particles is a common process in energy industries and chemical engineering. Understanding the fluidization important to guide relevant processes. There already have been numerous studies which investigate behaviors different during fluidization, but investigations polyhedral do not receive much attention. In this study, investigation described by polyhedron approa...

We use numerical modeling to investigate the combined effects of impact velocity and acoustic fluidization on lunar craters in the simple-to-complex transition regime. To investigate the full scope of the problem, we employed the two widely adopted Block-Model of acoustic fluidization scaling assumptions (scaling block size by impactor size and scaling by coupling parameter) and compared their ...
