4 Cross-Flow-Induced-Vibrations in Heat Exchanger Tube Bundles: A Review Shahab Khushnood et al. * University of Engineering & Technology, Taxila Pakistan 1. Introduction Over the past few decades, the utility industry has suffered enormous financial losses because of vibration related problems in ...
Vibration-induced endangers smooth running of a heat exchanger.This paper,inaccordance with the random vibration theory,deals with flow-induced vibrations ... DJ Gorman 被引量: 3发表: 1977年 Prevent flow-induced vibration in heat exchangers Optimization of an existing process plant sometimes referred...
Flow-induced vibration, or vortex shedding, is due to high flow velocities such as in a piping dead leg of a centrifugal compressor system. This study evaluates vortex shedding and potential vibration across dead leg branches. The study can also include FIV excitation of small-bore piping and ...
Early texts on heat exchanger rating methods [16.1.l–2] acknowledged the dominance of the single segmental baffle design. It was not until the '60's, when widespread failure of tubes began to occur [16.1.3], that another consequence of shellside cross flow — flow induced vibration — ...
