Numerical simulation results and related laboratory test are in good accordance, it bear out that researching the It has been demonstrated that it is comparatively reasonable and effective to carry out research on the mechanism of mud membrane formation at a meso-scale level.
Based on the study of particle flow to the characteristics of the mesoscopic medium particle flow and the formation mechanism of mud membrane, numerical simulation of the mesoscopic particle flow was adopted to assist laboratory tests and finally obtained fairly reasonable results.
In order to be compared with the results of laboratory tests, 34 groups of numerical simulations are conducted in 5 different strata, and the specific test groups are shown in Table 3.
