Research on the characteristics of coal-water slurry flowing through the local pipe fittings is of great significance to the industrial application and design of coal-water slurry pipelines. The paper has carried on a more comprehensive exposition to the research method of the resistance characteristic of the coal-water slurry flowing through the local pipe fittings, including some research progress on its influencing factors, experimental methods, numerical simulation and experimental result analysis. At the same time, the author also put forward some new ideas on the geometric definition, differential pressure analysis and resistance characteristic parameters of partial tubes, and made some prospect on the research on the resistance characteristics of CWM in partial tubes.
