Modelling of Spouted and Spout-Fluid Beds: Key for Their Successful Scale Up

The Effect of Interparticle Cohesive Forces on the Fluid Flow Simulation in Spout-fluid Beds

As reflected in the literature, solid-fluid flow characteristics in spouted beds can vary widely when particles are coated by a suspension. This work is aimed at describing the effect of interparticle forces on airflow distribution in conical spouted beds of inert particles coated by Eucalyptus black liquor. The simulator developed earlier is modified to incorporate this effect. Two corrective ...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Mathematical Modelling for Hydrodynamic Studies of Spouted Bed

The hydrodynamic behaviour of the spouted bed has been studied by considering the different system parameters (viz. static bed height, spout diameter, particle size, gas velocity and particle density). Experiments were carried out using a Perspex column of 4 inch diameter. Attempts have been taken to develop correlations for the bed expansion / fluctuation ratios by varying different system par...

Prediction of Minimum Spout Velocity and Moisture Distribution of Ammonium Perchlorate Particles in a Spouted Bed Dryer

Ammonium perchlorate particles have been dried in a laboratory spouted bed dryer (screen-bottomed type) which is categorized as a fluidized bed dryer. The solid particles obtained in this process of drying were semi-porous and known as the group D of Geldart classification. The variations of moisture content with resident time, the effects of bed height on the pressure dro...

Optimization of Spouted Bed Scale-Up by Square-Based Multiple Unit Design
