| 摘 要： | 以普兰德动量传递理论为基础,按照卡门的三层模型,通过室内模拟环道用0号柴油及加入减阻剂在圆管内的流动参数的测定,计算了非牛顿型流体管内湍流边界层的层流内层、过渡层、湍流中心的涡流粘度,涡流粘度与运动粘度比、总应力随相对位置的变化等定量参数,探讨了高分子减阻剂对非牛顿流体流动特性的影响,对湍流减阻现象的机理与增大减阻率的条件进行了定量分析.

| Abstract: | Based on Prandtl' s momentum transportation, this paper calculates in detail the physical quantities such as eddy viscosities,and ratio of eddy viscosity to motion viscosity, total stresses with respect to relative position in three regions of viscous sub-layer, buffer layer,and main turbulent stream for non-Newtonian fluid flowing turbulently in ducts,which according to Karman's three layer models and measurement of fluid parameters in evaluation apparatus, discusses the influence of polymer drag reduction on flowing properties of non-Newton fluid, analyzes quantitatively principle of turbulent reduction phenomenon and condition of increasing reduction rate. |
