英文摘要: Abstract(#br)Three types of relatively high-molecular polymer were used to investigate drag reduction in single-phase flow through a horizontal, 12.7-mm pipe. Diesel oil and a mixture of diesel oil and model oil were employed as the oil phase. The effect of various factors on the drag reduction rate was investigated. These factors included the oil and drag reducer polymer type, polymer concentration, Reynolds number, temperature, and shear under turbulent flow (Reynolds number: 3000–12000). The experimental results indicated that the drag reduction rate increases initially (when the polymer concentration increases from 1 ppm to 4 ppm) and then stabilizes at some maximum value. The maximum rate occurred at the maximum concentration (i.e., 5 ppm) in the experiment considering the diameter...
