The simulation result showed that this method can satisfy the requirement of precision and provide reference for the analysis of the flow field which had the established relationship between structural parameters and laminar flow within it.
CFD software based on Finite Element Analysis is commonly used to analyze such flow field.
CFD geometry with multi-plate, simplified CFD geometry and their meshing graphs The setup in ANSYS® FLUENT® is as following: laminar model, density is 998.2kg/m3, viscosity is 0.001003kg/m –s, velocity magnitude of inlet is 0.000381m/s.
The results of simulation showed that the range of errors was small enough between two solutions, and it can meet the requirements of practical application.
This simplified method provided alternate means for some CFD research field that could be analyzed indirectly.

Gas-solid flow behavior of the bottom zone of a 65t/h High-low bed CFB was simulated using the commercial computational fluid dynamics (CFD) software package Fluent.
Nowadays, with the enhancement of computer performance, CFD models have enjoyed great development.
Yu qing feng [4], Wang qinggong [5] study the gas-solid two phase flow of High-low circulating fluidized bed via numerical simulation with EEM model. 2D CFD simulation of gas-solid flow profile of the bottom zone of the High-low bed CFB is performed using EEM incorporating the kinetic theory of granular flow in this study.
Simulation Settings The 2D geometry of the dense zone is shown in Fig. 1.
In addition, a constant time step of 5e-4 s was used, and the simulation was performed for 5s of real fluidization time.

Abstract.
This paper presents a new way for performing numerical simulation for the three-dimensional inner flow field analysis of new inflatable cover and blackbody radiation source cavity by using the FLUENT software of CFD.
