从非牛顿流体运动微分方程式出发，利用积分、级数展开和数值计算方法，对剪切稠化流体（n=2）在环形通道中的流动进行了分析和计算，推出了该流体在环形通道中流动的速度、流量、平均速度和平均应变速度等关系式，绘制了几种不同R1／R2比值条件下的流体在管道横断面上的速度分布图，讨论了压力降与流量、速度与环管半径之间的关系，为工程计算提供了可靠的理论依据。
Based on the differential equation of motion of non-Newtonian fluid, the flow of the shear-thickening fluid (n = 2) in the annular channel was analyzed and calculated by using integral, series expansion and numerical calculation. Flow rate, average velocity and average strain rate, the velocity distribution of fluid on the cross section of pipelines is plotted under several different R1 / R2 ratios. The relationship between pressure drop and flow rate, velocity and ring The relationship between tube radius provides a reliable theoretical basis for engineering calculation.
