基于流固耦合的U型管流致振动数值分析
Numerical Simulation of Fluid-Induced Vibration in U-Tube Based on FSI
摘要
Abstract
Fluid-induced vibration of U-tube was analyzed by two-way FSI with ANSYS and CFX software. Large eddy simulation model and structural vibration model were built, obtaining the time-dependent lift coefficient, drag coefficient of the fluid flowing past U-tube and the vibration acceleration level of U-tube. The results show the primary frequency of structure vibration is near to the frequencies of left and drag and the natural frequencies of U-tube. Numerical simulation results can support the engineering practice.关键词
