Resistance mechanisms and resistance reduction of slurry in pipeline

Abstract

Resistance of slurry in pipeline is an important parameter in designing a slurry-conveying pipeline, which affects the cost of transportation of slurry. Therefore, it is of importance to study the resistance mechanisms, and to adopt proper technologies in reducing the resistance of slurry in pipeline. Resistance mechanisms of both fully stratified flow and fully suspended flow were discussed on the basis of analyzing the flow state of slurry in pipeline home and abroad. Technologies of reducing the resistance by adjustingthe sizes of particles, adding resistance reducer and rising temperaturewere summarized considering the influencing factors on resistance of slurry in pipelines.
