Abstract
In the present work, a new, additive-free technique for enhancing the flow in pipelines is introduced. This technique utilizes an inserted turbulence-altering pseudo-surface, with certain dimensions inside of the pipe (adjacent to the inner wall). This technique is meant to investigate the viscoelastic behavior of soluble additives to enhance the flow in pipelines. A liquid circulation system with a testing section divided into four subsections was used to test the drag reduction effect of the new technique. The results showed that nearly 60% flow enhancement is achievable when inserting 12 strips with lengths of 60 cm into a 0.0381-m diameter pipe.
