Drag Reduction
Drag reduction is a remarkable ability to reduce the frictional resistance in the turbulent flow by adding a low concentration of certain additives, drag reducing additive agents (DRA). Several studies have been carried out on reducing the friction factor in flow system using different drag reducing agents. High costs of fluid transportation (such as pumping the liquids into the pipelines) in production processes has made drag reduction subject of lots of research in the past decades.
The purpose of this study is to investigate the effects of different additives on drag reduction using various methods. However, there are a few investigations carried out on the effects of combining two or more DRAs. Effects of Polymer, Air bubbles, Aerofroth, and their combination have been investigated through the experimental
