Drag reducing agent

Drag reducing agent - Wikipedia

Introduction Drag is one of the most fascinating concepts in the aviation industry today. Dating back to the late s, near the World War II, the concept was given much importance since scientists were working on ways to make flight and aerial combat more effective. As time progressed, various methods to reduce drag were introduced since it can influence the future of aviation. Drag reduction methods have many positive ramifications like higher operational range, fuel consumption reduction,. The intention of this research is to clearly define the roles that drag performers fill in our society.

Drag-reducing agents DRA , or drag-reducing polymers DRP's , are additives in pipelines that reduce turbulence in a pipe. Usually used in petroleum pipelines , they increase the pipeline capacity by reducing turbulency and increasing laminar flow. Drag reducing agents can be broadly classified [2] under the following four categories — Polymers , Solid-particle suspensions , Biological additives, and Surfactants. These agents are made out of high molecular weight polymers or micellar systems. The polymers help with drag reduction by decreasing turbulence in the oil lines.
Title: Transient aspects of the polymer induced drag reduction phenomenon. Over the years, numerous experimental and numerical studies have been conducted in attempts to make practical use of polymer-induced drag reduction, including long-distance transport of liquids, oil well operations, firefighting, transport of suspensions and slurries, and biomedical applications. The polymers successively stretch and coil by interacting with the turbulent structures, which changes the turbulent flow and further imposes a transient behaviour on the drag reduction DR as well as the subsequent mechanical polymer degradation.
