Downer reactor, in which gas and solids move downward co-currently, has unique features
such as the plug-flow reactor performance and relatively uniform flow structure compared to …

Because of the importance of multiphase flows in a wide variety of industries, including
power, petroleum, and numerous processing industries, an understanding of the behavior …

The Multiphase Flow Handbook, Second Edition is a thoroughly updated and reorganized
revision of the late Clayton Crowe's work, and provides a detailed look at the basic concepts …

A U-type reduction chamber (URC) is developed as the key component of the novel iron ore
suspension roaster. It consists of a fluidization chamber (FC) and a supply chamber (SC) …

A three-dimensional CFD model was developed to simulate the hydrodynamics in a pilot-
scale dual fluidized bed system for biomass gasification. The system includes a fast fluidized …

A CFD simulation was performed to evaluate the performance of a novel multiregime gas–
solid fluidized riser reactor that was designed to maximize the propylene yield from the …

The application of high density and high solids flux CFB risers for steam gasification of solids
fuels like coal and biomass has been examined in this paper. A simple mass and energy …

This study presents the results obtained from the operation of a 20 kWth in situ gasification
chemical-looping combustion (iG-CLC) unit with a Chinese bituminous coal as the fuel and …

Many fuel conversion technologies using dual fluidized bed (DFB) have been developed,
including the chemical looping combustion (CLC), CO2 acceptor, and DFB pyrolysis or …

A novel large-scale triple-bed combined circulating fluidized bed (TBCFB), consisting of a
riser (16.6 m in height, 0.10 m inner diameter), a downer (6.5 m in height, 0.10 m inner …
