摘要 依据非牛顿流体力学原理,推得了卡森液体(Casson Fluid)圆管层流螺旋流流场中的视粘度函数、速度分布函数:建立了流量、压降的解析方程式;运用Hanks的稳定性理论,给出了判别卡森液体圆管螺旋流流动状态的稳定性参数J及其最大值J_(max)的表达式。通过实验验证了所得的理论结果。 The analytical expressions for the apparent viscosity and velosity distri-bution of the helical laminar flow of Casson fluid in pipes have been derivedbased on the fundamentals of Non - Newtonian fluid mechanics. The equationsof the flow rate and pressure drop are established. Using the stability theoryof Hanks, the expressions for the stability parameter J characterizing thetransition from laminar flow to turbulent flow and its maximum value J_(max)are given. All theoretical results are supported by experiments.
