基于计算流体力学与离散元法耦合(CFD-DEM)的模拟方法,以实现最高流场均匀度为目标,探究了导流锥结构对流场均布的影响.在获得最优导流锥结构的基础上,进一步研究了反应器高径比(I)、开孔率(?)和内外流道截面比(S)对流场均布的影响.结果表明:导流锥形状系数a和n均取1.00时反应器内流场均匀度最高;高径比、开孔率和内外流道截面比较小有利于流场均布;正交实验表明,开孔率对流场均匀度影响最大,反应器最优结构为高径比取4、开孔率取0.055、内外流道截面比取0.2.
To achieve the highest flow field uniformity
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
?=0.055 and S=0.2.
