摘要 推导出了普遍适用的非牛顿流体紊动微分方程武.在此基础上,导出了适用于圆管的运动微分方程式。据此研究了非牛顿流体圆管紊流流场及两种非牛顿流体在圆管中的顶替规律。 In the paper, first of all, the widely suitable turbulent differential equation for non-Newtonian fluid has been proposed. Then, based on that, the turbulent motional differential equation for a pipe is made out From that, the turbulent flow and displacement laws for non-Newtonian fluids in a pipe have also been studied.
