Formulating drag reducing agents' (DRA) average concentration and corresponding drag reduction efficiency can show that mechanical degradation of DRA not only occurs after its dissolution but also ...
ALTHOUGH many detailed investigations have been made of the drag reduction in pipe flow caused by polymer additives, very little quantitative information is available about the effect of polymers on ...
Suspension-based drag-reducing agents (DRAs) have proven to be an alternative to gel-based technology for ConocoPhillips Pipeline Co.’s US crude pipelines. This article examines data from one of ...
