Résumé

Ice fixation on the pipe surface causes the blockage accident of ice slurry flow. In this study, we observed behavior of ice slurry flowing in transparent tube and investigated the ice fixation, which caused by adhesion and accumulation of ice particles. We focused the fixation at a contraction part, because the fixation seems to occur around valves or joint parts of the pipe. From the results of the experiment, we suppose the adhesion (initial ice fixation) and the accumulation (growth of the fixed ice) results from the different reasons. As the special feature of ice, the flow condition in front of the contraction part affects the ice fixation. Because of large adhesion force of ice, the block ice flowing from upper stream stacks at the contraction part and leads the ice accumulation.
