What is Application of the Energy-minimization Multi-scale Method to Gas–liquid–solid Fluidized Beds about?
A model for gas-liquid-solid three-phase uidized beds with concurrent gas-liquid up-ow is proposed, which is formulated on the basis of the energy-minimization multi-scale (EMMS) method for gas-solid two-phase ow. The three-phase uidization system is resolved into the suspending and transporting subsystem and the energy dissipation subsystem, and the former is further divided into three sub-subsystems: liquid-solid phase, gas phase and inter-phase. Force balance is analyzed at three di erent scales: micro-scale of particles, meso-scale of bubbles and macro-scale of the whole system. In addition to the analysis of multi-scale interactions, the energy consumption in the system is analyzed to establish the stability condition for the system, which is considered indispensable due to the multiplicity of three-phase uidized beds. The total energy of the system consumed with respect to unit mass of particles is resolved into two portions: suspending and transporting energy and dissipated energy. The stability condition is reached when the suspending and transporting energy of the system, Nst, is at its minimum. The model ÿrst formulated as a nonlinear programming problem consisting of six
