agglomeration of particles

Particle Agglomeration an overview ScienceDirect Topics

Understanding particle agglomeration and aggregation and the mechanisms that cause such assemblies is important in a wide range of processes and applications. Aggregation and agglomeration are two terms that are used to describe the assemblage of particles in a sample. Although these two terms have distinct meanings, they have been used

Agglomeration of Particles SpringerLink

Each of the particles acts on the other particles and at the same time is exposed to their action. Their interaction agglomerates them into higher units, forms systems of elementary particles and is thus responsible for structure and evolution of the universe.

Agglomeration of fine particles subjected to centripetal

2008-5-6  Agglomeration of fine particles was studied by DEM with focusing on the effect of particle size on the agglomerate structure and strength. The results showed that both packing density and coordination number decay exponentially to their planar limits as agglomerate size increases, and structural properties are dependent on the interparticle force.

Agglomeration of sub-micron particles by a non-thermal

2014-2-1  Particle agglomeration is a process where the sub-micron particles are adhered to form a larger one which can be detected and removed easily. Many agglomeration techniques have been proposed such as: I) the injection of chemicals into gas streams to increase the agglomeration of sub-micron particles, II) the use of laminar flow precipitators to

Agglomeration of Titanium Dioxide (TiO2) particles

2021-6-1  Agglomeration of particles is a complex phenomenon, dependent on multiple aspects. One of those determining factors is the roughness of the primary particle. A slight degree of denting in the TiO 2 particle surface can lead to larger agglomerates that are harder to break, compared to spherical, smoothed surfaces. Such conclusions can help

Sonic agglomeration of aerosol particles SpringerLink

Carbon black was used to study the behavior of an aerosol in a sound field. The primary objective of this work was to determine the feasibility of using sonic agglomeration at low sound pressure levels (100 to 120 dB) to coagulate particles. If coagulation could be achieved, the larger particles could be collected in a subsequent removal device. Prediction of optimum conditions for maximum

Modelling of the agglomeration of Ni-particles in anodes

The degradation of anodes of solid oxide fuel cells (SOFC), which consist of a porous metal − solid electrolyte material is described by a two particle model. The model is based on two main assumptions. Firstly, the difference in metal particle diameter is the driving force for the observed coarsening of the larger metal particle during long term annealing.
