Interparticle Van der Waals force contributes to the overshoot in bed pressure drop at minimum fluidization velocity during transition from static fluidized conditions, which is a well-known phenomenon of fine particles. In this study, two adhesive particle closures considering effect interparticle are used two-fluid model simulations with intention generate overshoot. The first developed within context kinetic theory rapid granular flows failed produce due dominance multiple and long...
This paper demonstrates a new concept of heat transfer fluid (HTF) for CSP applications, developed in the frame both National and European project (CSP2 FP7 project). It involves dense suspension small solid particles. innovation is currently. The particles receiver (DSPR) consists creating upward circulation (solid fraction range 30%-40%) vertical absorbing tubes submitted to concentrated solar energy. So acts as with capacity similar liquid HTF but only limited temperature by working limit...
Abstract This paper focuses on a new concept of Heat Transfer Fluid (HTF) for Concentrating Solar Plants (CSP) applications through fluidized bed. CSP plants with very high concentration (such as solar tower plant technology) offer good efficiencies because operating temperatures. efficiency could be greatly increased more efficient HTF. Molten salts, mineral oils, water and air have some the following drawbacks: limited range temperatures, corrosiveness, pressure, low energy storage...
Sulphur dioxide (SO2) is mostly emitted from coal-fueled power plants, waste incineration, sulphuric acid manufacturing, clay brick plants and treating nonferrous metals. The emission of SO2 needs to be abated. Both wet scrubbing (absorption) dry or semi-dry (reaction) systems are used. In the process, both bubbling circulating fluidized beds (BFB, CFB) can used as contactor. Experimental results demonstrate a SO2-removal efficiency in excess 94% CFB application. A general model...
In two-fluid simulations of gas–solid fluidised beds, the gaseous phase and particulate are modelled as continuous media. The stress exerted by medium on container walls should be to predict accurately bed dynamics. This paper addresses modelling sliding particle–wall contacts in simulations, based reference coupling computational fluid dynamics with discrete element method (CFD-DEM), which individual movement particles is tracked. analysis CFD-DEM highlights complex near-wall behaviour...
Solid particles can be used as a heat transfer medium in concentrated solar power plants to operate at higher temperature and achieve conversion efficiency than using the current fluids that only work below 600°C. Among various particle circulation concepts, dense suspension (DPS) flow tubes, also called upflow bubbling fluidized bed (UBFB), was studied frame of CSP2 FP7 European project. The DPS capacity extract from tube absorber exposed radiation demonstrated first values wall‐to‐DPS...
