| In long distance slurry pipeline transport project, Speed transportedoften involve the energy consumption. So it is very important to study the critical speed in slurry Pipeline transportion, but up to now , the research about this aspect is not much. On the basis of research resul'ts of the existing experts and scholars especially the theory put forward by professor Xu zhenliang(my tutor) that predicts the velocity profiles and friction loss of settling slurry when it flows in horizontal pipe, relations among the velocity of water , that of solid particles and that of settling slurry have been established by the analysis of momentum transmission process between water and solid. Then the calculation model of the critical speed for Settling slurry in horizontal Pipeline transportion are derived.At last related data have been used to verify the the derived the calculation model. And it turn out that calculating results accord with actual results,so the calculation model can serve as helpful reference for operating and designingin this field. |
