Discrete Liquid Flow Behavior in a 2D Random Packed Bed

Behavior of Packed Bed Thermal Storage

A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...

Measurement of Liquid Velocity and Liquid Distribution in a Packed Bed Using Electrical Resistance Tomography

Hydrodynamic Behavior of Particles in a Jet Flow of a Gas Fluidized Bed

Numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. However, most of them address the problem from  macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. The present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle leve...

Surveying Denitrification Efficacy in Up-Flow Packed Bed Bioreactor Operated under Heterotrophic Condition Using Autotrophic Bacteria

Introduction: The biological denitrification process is an interesting cost-effective technique to remove nitrate from water supplies. Acetic acid can be used as a carbon source in this process, but its consumption rate is a critical issue and, in some cases, it is quite different from stoichiometric constants. The current study aimed to investigate the nitrate removal in an up-flow packed bed ...

Analysis of the Flow Behavior of Single and Multiphase Liquid in Packed Columns

In recent decades packed columns have become very popular for distillation processes since they acquire higher loadings and a better separation efficiency than ordinary tray columns. Fluid dynamics cover an important place in the design of packed towers. Identifying the main quantities remains subject of various research works. There exists a wide range of different approaches to determine the ...
