Drag Reduction by Polymers in Multiphase Flow in Pipes: DRPs Mechanism - Softcover

Inhaltsangabe

Multiphase flow industrial applications require reduced frictional pressure drop (drag) and lower operating costs. Drag reducing polymers (DRPs), which do not require additional infrastructure, meet this requirement. Therefore, this book investigated the effects of water-soluble and oil-soluble DRPs on pressure gradient and percentage drag reduction using Multiphase flow. The conduit comprised a 22.5 mm I.D. and 2.48 m long horizontal pipe. The fluid flow pattern and DRP shear stability were also investigated. The functional mechanism of DRP, not adequately addressed in the literature, was especially revisited. This work suggests that the resultant interaction between the DRP state and the external environment dictates its ability for dampening turbulent eddies, streamlining the velocity field, and eventually increasing the thickness of the laminar sublayer.
