Reference number : GC-2017-Q3-00542, amendment number : , agreement type : G, recipient legal name : Ghaemi, Sina (University of Alberta), recipient country : CA, recipient province : nan, recipient city : Alberta, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Pipelines are essential to the transport of thousands of tons of slurry and petroleum products in Canada. The_x000D_
hydro-transport pipelines can be hundreds of kilometers long and require several pumping stations to overcome_x000D_
the friction force between the fluid and the pipe wall. It is well known in the industry that the addition of a_x000D_
small amount of long-chain polymers to the can reduce friction drag by up to 70%, and consequently reduce the_x000D_
pumping costs. However, the polymeric additives need to be compatible with the shear rate of the flow and the_x000D_
chemical composition of the fluid._x000D_
The objective of the proposed research program is to investigate the drag reduction performance of SNF_x000D_
polyacrylamide products as a collaborative project between SNF and the Laboratory of Turbulent Flows (LTF)_x000D_
at the University of Alberta. The SNF team is interested to further understand the relation between ionicity,_x000D_
molecular weight, and macromolecular architecture of their polyacrylamide polymers for drag reduction in_x000D_
hydraulic applications. The preliminary experiments will be carried out in a Taylor-Couette device for_x000D_
accelerated tests using a small polymeric solution in the presence of solid particles. A slurry flow loop with_x000D_
high Reynolds number will be applied to investigate the magnitude and duration of drag reduction using_x000D_
polyacrylamide in slurry flows with different composition of particles and ionicity._x000D_
The proposed research will provide practical guidelines for development of high performance polymer drag_x000D_
reducers. The long-term goal of the research program at LTF is reduction of skin-friction, and development of_x000D_
efficient and environmentally friendly pipelines for slurry and petroleum transport in Canada., program purpose french : Pipelines are essential to the transport of thousands of tons of slurry and petroleum products in Canada. The_x000D_
