| Popis: | In order to study the flow characteristics of seawater-ice crystals two-phase flow in the polar cruise seawater pipeline system, the curved pipe in the pipeline system is taken as the research object. Through numerical simulation, the effects of different initial conditions on the flow of seawater-ice crystal two-phase flow in curved pipe are analyzed, and the flow analysis results are obtained. The results show that in the curved pipe, the fluid is separated at the bend, and the pressure loss at the corner of the curved pipe is the most serious; the increase of the flow rate and the IPF (ice packing factor) will cause the ice crystals to gather toward the center; when the fluid has a high IPF, the ice crystals can be converted into a symmetric distribution state by being concentrated on the inner wall surface of the pipe at a relatively low flow rate; in the range of 0.5 m/s-2 m/s, the increase in fluid velocity has a significant effect on the distribution of ice crystals, and when the fluid velocity exceeds 2 m/s, the increase in flow rate has no significant effect on the distribution of ice crystals. |
