Multiscale combustion and turbulence
Abstract Multiscale physics is the interaction of different physical processes occurring at largely separated scales. In combustion, many elementary reactions combine to only a few, but still have separated time scales. In flames, owing to the...

Packing Fixed Bed Reactors with Cylinders: Influence of Particle Length Distribution
Abstract In this work, we are interested in a better understanding of the local packing structure of fixed bed reactors made of cylindrical pellets packed in cylindrical tubes. Packing of cylindrical particles is simulated using Grains3D DEM code...

Effect of surface energy on the transition from fixed to bubbling gas-fluidised beds
Abstract Two-dimensional DEM–CFD simulations have been performed in order to examine the effect of surface energy on the transitional behaviour from fixed bed to bubbling bed for Geldart Type A particles. The results of the simulations presented in...

Hydrodynamics of a Large-scale Mixed-Cell Raceway (MCR): Experimental studies
Abstract The Mixed-cell Raceway (MCR) is a design that intends to combine the best characteristics of circular tanks and linear raceways in a single production system. The conceptual idea is to convert traditional linear raceways into a series of...

Combined manganese/iron oxides as oxygen carrier for chemical looping combustion with oxygen uncoupling (CLOU) in a circulating fluidized bed reactor system
Abstract Two kinds of particles consisting of mainly manganese and iron oxides have been examined as oxygen carrier for chemical-looping combustion with O2 uncoupling in a circulating fluidized-bed reactor. The first was produced by spray drying and ...

Maximization of capillary trapping ratio to injected CO2 by means of co-injection
Abstract Co-injection of water with CO2 is an effective scheme to control the initial gas saturation in porous media. The fractional flow rate of water about 5 to 10% is enough to reduce the initial gas saturations, and after water injection, most...

Using chemical-looping with oxygen uncoupling (CLOU) for combustion of six different solid fuels
Abstract Chemical-looping with oxygen uncoupling (CLOU) is a novel method to burn solid fuels in gas-phase oxygen without the need for an energy intensive air separation unit. This paper presents batch laboratory fluidized bed CLOU tests where six...
