DOI: 10.1016/j.powtec.2019.07.044
Abstract: Abstract The interactions of gas and solids are important in determining the flow structures in the Circulating Fluidized Bed (CFB) downer. Proper description of the interphase drag model is thus crucial for simulating the downer.… read more here.

DOI: 10.1016/j.powtec.2020.02.047
Abstract: Abstract Pressurised circulating fluidised bed (PCFB) is a new technology for coal/biomass combustion and gasification. To design, optimise and scale-up of PCFBs, it is necessary to understand the complex gas-solids flow characteristics. In this research,… read more here.
