Numerical Simulation of Gassolid Twophase Flow Characteristics in Bubbling Fluidized Bed

In order to study the gas-solid two-phase flow characteristics in bubbling fluidized bed reactor, the numerical simulation method, the Fushimi, to simulate the process of cold experiments, we set up reasonable TBCFB gasifier model of gas-solid two-phase flow, based on eulerian two-fluid model, neste...

description In order to study the gas-solid two-phase flow characteristics in bubbling fluidized bed reactor, the numerical simulation method, the Fushimi, to simulate the process of cold experiments, we set up reasonable TBCFB gasifier model of gas-solid two-phase flow, based on eulerian two-fluid model, nested FLUENT17.0 with ANSYS, as the basis of numerical simulation platform, the simulation TBCFB (level 3 fluidized bed gasifier bubbling fluidized bed gas-solid two-phase flow in the system process and analyze the flow characteristics. The results are mainly divided into three parts: the surface velocity of the bubbling bed has an important influence on the flow quality, and the lower the speed, the more favorable the bubbles in the bed are in contact with the bed material. It is found that the higher the height of the bed is, the higher the particle temperature is. The particle concentration increases, the particle temperature decreases, and vice versa.
