In this paper, a liquid-solid coupling method combining CFD and DEM is proposed to study two-phase flow behavior of water, The flow characteristics of water-clay mud and the motion characteristics of gravel were simulated under different discharge pipe bending radii and geometry shape conditions. Numerical results showed that for a circular cross section pipe with a fixed bending radius, the collision times between the gravel particles and the pipe wall decreased with the increase of the bending radius.}, doi = {10.1080/15502287.2020.1809554}, eissn = {1550-2295}, issn = {1550-2287}, issue = {5}, journal = {International Journal for Computational Methods in Engineering Science and Mechanics}, pages = {231-242}, publicationstatus = {Published}, publisher = {Taylor \& Francis}, url = {https://uwe-repository.worktribe.com/output/7263332}, volume = {21}, keyword = {Computational Mechanics, Computational Mathematics}, year = {2020}, author = {Chen, Lumin and Liu, Kaixuan and Yao, Yufeng and Yao, Jun and Su, Zixue and Luo, Guofu} }
