摘要
在直径为2.46和5.96mm的管子中.雷诺数为6×10~3～11×10~4的范围内,测定了粘弹性聚合物国产聚丙烯酰胺(PAA)的减阻特性。研究了减阻剂浓度、管径、盐类、温度等因素对减阻的影响,比较了几种不同型号PAA产品的剪切稳定性,探讨了减阻机理,为减阻剂的选择提供了基础数据。
The property of drag reduction of visco elastic polyacrylnmide solution was measured within a rather wide rang of Reynolds number in tubes. The effects of solution concentration.tube diameter. Reynolds number, temperature, type of salts,and shear degradation on the property drag reduction of polyacrylarnide solution were investigated. The drag reduction mechanism was discussed.
