Web15 de ago. de 2024 · The erosion is caused when these particles, dragged by the fluid, hit violently the wall of the pipe, begin able to remove part of its material. On the other hand, multiphase flows usually contain acidic chemical components, such as CO2 or H2 S, dissolved in the aqueous phase. Web31 de dez. de 2010 · Abstract: Small-, medium- and full-scale experiments are performed to investigate the process of backward erosion piping and to validate the model of Sellmeijer. The observed processes are described in this article and are divided in four phases: seepage, backward erosion, widening of pipe and levee failure.
