含空冷器管道系统气柱固有频率研究
Study on gas natural frequency of pipeline system with air cooler
摘要
Abstract
A simple air cooler model is designed and manufactured based on conventional air coolers used in engineering and the national standard of GB/T-15386-94.The pipeline with the air cooler experimental system is constructed,and the fluid dynamics of the piping system is mod-eled.Comparing the numerical results with test data,it can be found that both the experimental method of frequency sweep and the numerical simulation method of frequency response are cor-rect and reasonable.The parametric model of the air cooler as a special pipe component is pro-posed based on the results of experiment and simulation,which is named as “Volume-Pipe-Vol-ume”model.It provide a direct and effective method for calculating the gas natural frequency of pipeline system with air cooler.关键词
