the structure of the guide cone and reactor ratio of height to diameter(I)
the pipe porosity(?) and cross-sectional area ratio of central pipe to annular channel(S) are studied based on computational fluid dynamics and the discrete element method coupled(CFD-DEM) simulation method
the data of flow field inside the reactor are extracted. The results show that the guide cone with shape coefficients a=1.00 and n=1.00 has the highest uniformity of flow field in the reactor. When I
? and S are smaller
it is more conducive to the uniform distribution of flow field. The orthogonal experiment showed that ? had the greatest influence on the flow field uniformity. The optimal structure of the reactor is as follows: I =4
