非牛顿流体边界层减阻流动研究

Study on Boundary Layer Drag Reduction of Non-newtonian Fluids

研究了四常数Maxwell-Oldroyd模型非牛顿流体边界层流动 ,给出了边界层内速度分布数值解 ,以及边界层厚度、摩阻系数沿程变化关系。为探讨高分子稀溶液管内流动减阻提供了理论依据。

Laminar boundary layer flow of four constants Maxwell oldroyd fluid is investigated. The velocity distribution in boundary layer, the thickness of the boundary layer are shown. The relation between friction factor, Reynolds number, the material functions of Non newtonian fluids is given. For the laminar flow of Non newtonian fluids some drag reduction, like turbulent flow, has been found.
