This method is suitable for studying the problem on the dispersion of solute matter in arbitrary fluid models where velocity distributions through a circular tube are known.
本方法适用于研究已知圆管流速分布的任意流体模型中溶质的分散问题。
Then it is used to solve the flow of PAM solution in a circular tube. The velocity and stress distributions obtained can be used for the three dimension numerical simulation in the future.
然后用拟谱法求解PAM水溶液在圆管中流动，得到速度分布、应力分布，为三维模拟作准备。
A circular tube-like gap (S1) in which a plating liquid (17) flows is formed between the tubular electrode placed in the hollow section and an inner peripheral wall (14) of the hollow section.
圆管状间隙（S1）在 放置在中空段内的管状电极与中空段的内周壁（14）之间形成，电镀液在该 间隙（S1）中流动。
