基于精细化建模的换热管涡激振动数值研究
A numerical study of vortex-induced vibration of heat exchanger tubebased on refined modeling
摘要
Abstract
To study the vortex-induced vibration behavior of a single heat exchange tube,we established a refined flow field calculation model based on a large eddy simulation.The structural dynamics equations using the HTT-α method.In combination with the local dynamic mesh deformation technology,the fluid-structure interaction calcula-tion model of the vortex-induced vibration of the heat exchange tube was obtained.To analyze and study the vibra-tion response,motion trajectory,and wake mode of the heat exchange tube at different reduced flow velocities,the flow field calculation and the structural field calculation models were fully verified using the flow around a fixed cyl-inder with a Reynolds number of 3 900 and Jauvtis&Williamson′s classical vortex-induced vibration experiment.The results show that the vortex-induced vibration calculation model accurately predicts the vortex-induced vibration behavior of a single heat exchange tube.This research provides an important reference for establishing a flow-in-duced vibration calculation model of the tube bundle structure.关键词
