With the increase of the pressure difference, axial flux increases, and when the pressure difference increases further, the pressure flow is prominent, and higher pressure difference leads to the disappearance of the vortexes, the flow between the cylinders is mainly characterized by pressure flow. 随着压差的增加,轴流量随之增加,随着压差的进一步增加,压力流的作用处于主导地位,压力流的增强最终导致涡胞消失,轴间流场特征主要表现为压力流。
Recycle tubular reactor model with axial dispersion leads to a special boundary value problem, in which one boundary condition involves the values at two end points. 一种循环管式反应器的扩散模型,归结为一类特殊的边值问题,其特点为两个端点的函数值出现在一个边界条件中。
