摘      要：During the pipeline plugging process,both the pipeline and the pipe isolation tool(PIT)will be greatly damaged,due to the violent vibration of the flow *** this study,it was proposed for the first time to reduce the vibration of the flow field during the plugging process by optimizing the surface structure of the ***,the central composite design(CCD)was used to obtain the optimization schemes,and the drag coefficient and pressure coefficient were proposed to evaluate the degree of flow field ***,a series of computational fluid dynamics(CFD)simulations were performed to obtain the drag coefficient and pressure coefficient during dynamic *** the mathematical model of drag coefficient and pressure coefficient with the surface structure of the PIT were established ***,a modified particle swarm optimization(PSO)was applied to predict the optimal value of the surface structure of the ***,an experimental rig was built to verify the effectiveness of the *** results showed that the improved method could reduce the flow field vibration by 49.56%.This study provides a reference for the design of the PIT surface structure for flow field vibration technology.
