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
摘要以普蘭德動量傳遞理論為基礎，按照卡門的三層模型，通過室內模擬環道用0號柴油及加入減阻劑在圓管內的流動參數的測定，計算了非牛頓型流體管內湍流邊界層的層流內層、過渡層、湍流中心的渦流粘度，渦流粘度與運動粘度比、總應力隨相對位置的變化等定量參數，探討了高分子減阻劑對非牛頓流體流動特性的影響，對湍流減阻現象的機理與增大減阻率的條件進行了定量分析。 -
