Friction factor for water flow through packed beds of spherical and non-spherical particles

Flow through Packed Beds and Fluidized Beds

Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...

Numerical simulation of effect of non-spherical particle shape and bed size on hydrodynamics of packed beds

Fluid flow has a fundamental role in the performance of packed bed reactors. Some related issues, such as pressure drop, are strongly affected by porosity, so non-spherical particles are used in industry for enhancement or creation of the desired porosity. In this study, the effects of particle shape, size, and porosity of the bed on the hydrodynamics of packed beds are investigated with three ...

Orientation of non-spherical particles in an axisymmetric random flow

llenges in packing problems: from spherical to non-spherical particles

HIGHLIGHT Adrian Baule and Hernán A. Makse Fundamental challenges in packing problems: from spherical to non-spherical particles Random packings of objects of a particular shape are ubiquitous in science and engineering. However, such jammed matter states have eluded any systematic theoretical treatment due to the strong positional and orientational correlations involved. In recent years progre...
