高分子减阻剂溶液流变参数的测定与分析

Determination and Analysis of Rheological Parameters of High Polymer Drag Reducer Solution

通过环道及流变实验数据,按照经验公式计算剪切变稠的油溶型高分子减阻剂在圆管中的流动情况,计算出柴油-高分子减阻剂溶液的流变参数Rew、τw、γw、ηw、fw,讨论其与减阻率DR%的关系。并推导出了对于溶液聚合的高分子减阻剂的摩擦系数与壁面雷诺数之间的关系:fw-12=29.8 log(Rewfw21)-54.43。

Some empirical equation were used to get Rew,τw ,γw,ηw ,fw. the relations of ηw, Rew, fw and DR% were discussed. 1 The equtation between Rew and fw was gained： fw^-1/2 =29.8 log（Rewfw^1/2 ） -54.43.
