Abstract

This work is targeted at making available some data to enhance the development of better predictive models for drag reduction (DR) in two-phase flows. Oil-water flows studies were carried out by using a horizontal acrylic pipe (14 mm ID) with tap water and a middle distillate oil the flowing liquids. A hydrolysed polyacrylamide served as the polymer in the water phase. Polyethylene oxide (PEO) with two different molecular weights was equally investigated. At an optimal polymer concentration of 20 ppm, drag was lowered as Reynolds number increased. While drag reduction was effectively described by models, it increased with polymer weight.

聚合物溶液降低流体流动中的压降

这项工作的目的是提供一些数据，以加强两相流减阻（DR）更好预测模型的开发。通过使用具有自来水和中间馏分油作为流动液体的水平丙烯酸管（14mm ID）进行油水流动研究。水解的聚丙烯酰胺作为水相中的聚合物。对具有两种不同分子量的聚环氧乙烷（PEO）进行了同样的研究。在20ppm的最佳聚合物浓度下，阻力随着雷诺数的增加而降低。虽然模型有效地描述了减阻，但减阻随着聚合物重量的增加而增加。

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
