摘要
减阻作用是在流体内加入少量添加剂,从而使输量增加的一种现象。本文介绍减阻率预测的有关经验公式,并以典型减阻实验数据为依据,得出减阻率DR和雷诺数Re、浓度PPM、管径ID之间的综合经验式。由此式可对温(粘)度变化范围不太大的同种减阻剂—溶剂体系,以室内二件小管径的实验数据来推算和预测放大管径的减阻率。
The drag reducing action is the way of injecting small amount of drag reducing agent into the fluid. So that is a phenomenon of increasing throughput. The paper introduces some experimental formulas for the prediction of drag reducing rate and obtains the compound experiential formulas among DR ( drag reducing rate), Re ( Reynolds number), PPM (concentration) and ID (pipe diameter) based on the typical data of drag reducing experiment. This formula may be used to evaluate and predict drag reducing rate of enlarged pipe diameter for the same system of drag reducing agent and solvent within the range of less varied tempre ture and viscosity based on the experimental data of two smaller inside diameter pipes.
