| description | The article presents an analysis of theoretical approaches to assessing the gravity pipeline efficiency in the transportation of water containing suspended solids (the sand). The attention is focused on application of the pipeline protective coatings used in their trenchless repair. Provision has been made of studying the problems of the removal of caked deposits on the pipe walls by creating a special pipeline textured inner surface, representing some kind of a relief, which favors the forced effect of flow turbulence in combination with the hydrophobic properties of the pipeline inner surface. The article presents the results of the research works on the creation of small-size hydraulic benches, which allow determination of the degree of the flow hydrophobicity and the transporting capacity along various textured surfaces (the pipeline protective coatings). The article describes the methods of work on the benches, types of obstacles and the nature of their arrangement along the length of the tray. Provision has been made of different options of the pipeline surface relief further improvement. The photo and film fixation, as well as the black-and-white shadow effects, have enabled presentation of the results of full-scale research experiments on the removal of various size suspended solids from the pipeline tray part. The micro-turbulence phenomena depending on the height of obstacles and their location have been described. The prospects and practical significance of the works aimed at improving the flow transport capacity have been assumed. |
