Application of a Numerical Experiment to Determine the Parameters of Pipeline Transport Depending on the Flow Stream Velocity

Abstract

This work considers the origins of hydrodynamic mechanisms of the excitation of pipe vibrations in a transversal flow of liquid. The suggested model of a numerical experiment is assigned for complete reproduction of all the main mechanisms of pipe vibration generation of pipe bundles, namely, periodic vortex separation, and hydroelastic excitation. An effective approach upon detection of a dangerous correlation of the structural parameters of a pipeline system for providing accident-free operation of a researched structure is described. The methodology suggested is based on the results of experimental and numerical study of pipe structures in a liquid flow.
