| Abstract: | According to the changing rules of heterogeneous slurry flow state with the increase of the mean velocity,considering the flow of multisized particulate slurries with wide range of particle diameters,and based on the condition of solid particle start action and the concept of deposit velocity,the measurement model of deposit velocity of commercial slurries in horizontal pipes is studied.The prediction of the deposit velocity of commercial slurries in horizontal pipes is satisfying. |
