摘      要：Numerical simulations of evolution characteristics of slug flow across a 90°pipe bend have been carried out to study the fluid−structure interaction response induced by internal slug *** two-phase flow patterns and turbulence were modelled by using the volume of fluid(VOF)model and the Realizable k−εturbulence model ***,validation of the CFD model was carried out and the desirable results were *** different flow patterns and the time-average mean void fraction was coincident with the reported experimental *** of different cases of slug flow have been carried out to show the effects of superficial gas and liquid velocity on the evolution characteristics of slug ***,a one-way coupled fluid-structure interaction framework was established to investigate the slug flow interaction with a 90°pipe bend under various superficial liquid and gas *** was found that the maximum total deformation and equivalent stress increased with the increasing superficial gas velocity,while decreased with the increasing superficial liquid *** addition,the total deformation and equivalent stress has obvious periodic ***,the distribution position of maximum deformation and stress was related to the evolution of slug *** the increasing superficial gas velocity,the maximum total deformation was mainly located at the 90°pipe *** as the superficial liquid velocity increases,the maximum total deformation was mainly located in the horizontal pipe ***,the slug flow with higher superficial gas velocity will induce more serious cyclical impact on the 90°pipe bend.
