Pipelines are essential to transport thousands of tons of bitumen slurries along with sand and clay in the oil sands industry of Canada. Pipelines deliver the mixture from the mine to the bitumen extraction and the upgrading plants for final conversion into synthetic crude oil. A remaining issue of slurry pipelines is the relatively short life-time of the pipes due to surface wear caused by the progressive removal of pipe material by the solid particles.**Researchers at Shell Canada have qualitatively observed that the addition of a low concentration of high-molecular weight polymers can reduce wear in various slurry flow equipment. This possible wear reduction technique is unexplored and requires detailed investigation to quantitatively assess the wear reduction capabilities. In addition, the wear reduction mechanism that is associated with the effect of polymers on the turbulent motion of slurry particles is not well understood. **This collaborative project between the Laboratory of Turbulent Flows of the University of Alberta and Shell Canada will carry out an experimental investigation to systematically quantify the wear rate of slurry pipes using a low concentration of long-chain polymer. The proposed project will investigate the effect of polymer type and concentration on pipeline wear caused by a broad distribution of particle size relevant to the slurry pipelines of oil sands industry. The program will also aim at fundamental understanding of wear mechanism by detailed investigation of the impact dynamics of particles using state-of-the-art particle tracking velocimetry. The long-term goal of the project is to increase the lifetime of long distance slurry pipelines and consequently reduce the environmental impact of the oil sands industry in Canada.**

在加拿大的油砂工业中，管道对于运输数千吨沥青浆以及沙子和粘土至关重要。管道将混合物从矿山输送到沥青提取和升级厂，最终转化为合成原油。泥浆管道的一个遗留问题是，由于固体颗粒对管道材料的逐渐去除造成的表面磨损，管道的寿命相对较短。**壳牌加拿大公司的研究人员定性观察到，添加低浓度的高分子量聚合物可以减少各种浆液流动设备的磨损。这种可能的减少磨损技术尚未被探索，需要详细的研究来定量评估减少磨损的能力。此外，与聚合物对浆料颗粒湍流运动的影响有关的磨损减少机制尚不清楚。**这个由阿尔伯塔大学湍流实验室和加拿大壳牌公司合作的项目将进行一项实验研究，系统地量化使用低浓度长链聚合物的泥浆管的磨损率。拟议的项目将调查聚合物类型和浓度对油砂行业泥浆管道中广泛分布的粒径造成的管道磨损的影响。该计划还将通过使用最先进的颗粒跟踪测速法对颗粒的冲击动力学进行详细调查，以基本了解磨损机制。该项目的长期目标是增加长距离泥浆管道的使用寿命，从而减少加拿大油砂行业对环境的影响
