多孔介质降低圆柱体涡激振动的数值模拟分析
Numerical Simulation of Vortex-Induced Vibration of Cylinder with Porous Media
摘要
Abstract
Vortex-induced vibration represents a critical mechanism of structural damage,which not only reduced service life of workpieces but can also lead to structural deformation and failure,thereby posing safety risks or causing economic losses.This study conducts a numerical simulation of vortex-induced vibrations in porous media cylinders using CFD software,employing the k-ω turbulence model and SIMPLE pressure-velocity coupling method.Simulations were carried out on single porous media cylinders,three porous media cylinders,and transversely arranged cylinders in matrix configurations to study vortex-induced vibration problems under various scenarios.By comparative analysis,the study examined the impact of porous media on cylinder vortex-induced vibrations in different arrangement scenarios.The results indicate that in all arrangement scenarios,the addition of porous media can result in uniform force distribution on the cylinders and a more stable flow field,effectively eliminating the occurrence of vortex-induced vibrations.This extends the service life of the workpieces,enhances efficiency,and demonstrates significant practical value and application prospects.关键词
