3D-modeling of variants inserts to reduce vibration of pipelines
https://doi.org/10.15518/isjaee.2020.10.011
Abstract
Vibrations of equipment and pipelines are an existing factor determining the power plants’ elements and pipelines failure. About half of all disturbances in the operation of pipelines are caused precisely by vibration. One of the reasons for its appearance is the interaction of the transported flow with the walls of the pipeline. In this case a device that dampens vibration, or preventing it may be a solution. The swirl inserts considered in this work for pipelines with a two-phase flow prevent the occurrence of vibration due to a more uniform distribution of phases along the cross section and length of the pipe. The experimental inserts were modeled in the SolidWorks CAD software package for 3d printing, as well as for preliminary tests in the field of computer modeling. Computer simulation of a single-phase fluid flow was performed using the Flow Simulation module. The result of the work is an insert for testing on a hydrodynamic bench created on a 3D printer. According to the results that will be subsequently obtained experimentally at the stand, it will be possible to judge the efficiency of the vortex, the probability of the current tearing off the insert wall and the resulting resistance, which is also important for a pipeline with two-phase media due to interphase transitions.
Modeling of inserts with various groove guides was performed. Using a 3D printer, prototypes were printed, with the help of which a primary analysis of the effectiveness of an insert with a specific geometry on an experimental bench is possible.
