摘要

摘要: 通过研究不同浓度、不同分子量的HPAM溶液的流变及摩阻性能，建立了一个聚合物溶液摩阻系数方程。测试了5种不同浓度、4种不同分子量的HPAM溶液的稳态剪切黏度、触变性、流动曲线等流变性能；并分别测试其在管内径为0.77 cm，流量为3～9 L/min的压差数据，计算得摩阻系数数据，分析了聚合物分子量、聚合物浓度等对溶液减阻的影响，建立了聚合物溶液摩阻系数f和广义雷诺数Re及聚合物溶液流型参数n之间的摩阻系数方程。

Abstract: An equation describing the friction of polymer solutions was developed through the studies on the rheology and friction of HPAM solutions of different concentrations and molecular weights of HPAM. HPAM solutions formulated with five different HPAM concentrations and HPAM with four different molecular weights were measured for their steady-state shear viscosity, thixotropy and flow curves. The friction data of the HPAM solutions were calculated by measuring the differential pressures of these solutions in a pipe with inner diameter of 0.77 cm at flow rates ranging between 3 L/min and 9 L/min. The effects of the molecular weight and concentration of the polymer on friction reduction of solution were analyzed. Based on these studies, a friction coefficient equation describing the relationship among the friction coefficient f, the generalized Reynolds number Re and the flow pattern index n of the polymer solutions was established.
