This work described the shear flow structure induced by a guided vane in the turbulent mixing layer of a liquid-liquid cyclone reactor. And the results show that the tangential velocity is much greater than radial velocity at the same axial section, which means the tangential velocity gives greater impact on the breakup of dispersed phase jet and droplet deformation. In addition, the variations of tangential velocity along radial, circumferential and axial directions were investigated. It was concluded that the tangential velocity increased firstly and then decreased with the radial position approaching the axis. The position of the peak tangential velocity along radial direction in the same axial position barely changed with the change of radian. But the peak tangential velocity value changed along the circumferential and axial directions, which attenuated in the form of power function along axial direction. Moreover, the tangential velocity showed a fluctuation along the circumferential direction. And the fluctuation of tangential velocity at the radial position of peak tangential velocity is more obvious. Besides, the amplitude of fluctuation gradually decreased with the axial section getting closer to the separation chamber. And a stable flow area was found at the axial section of z = 70~0 mm.

这项工作描述了在液-液旋流反应器的湍流混合层中由导向叶片引起的剪切流结构。结果表明，在同一轴向截面处，切向速度远大于径向速度，这意味着切向速度对分散相射流的破碎和液滴变形的影响更大。此外，研究了切向速度沿径向、周向和轴向的变化。得出的结论是，切向速度随着径向位置靠近轴而先增大后减小。同一轴向位置沿径向的峰值切向速度的位置几乎不随弧度的变化而变化。但切向速度峰值沿周向和轴向发生变化，沿轴向以幂函数的形式衰减。此外，切向速度显示出沿圆周方向的波动。且切向速度峰值处径向位置处的切向速度波动更为明显。此外，随着轴向截面靠近分离室，波动幅度逐渐减小。并且在轴向截面处发现了一个稳定的流动区域z  = 70~0 毫米。
