However, if LOF is more than 0.3 then corrective actions need to be taken to mitigate the vibration possibility. In most cases, a structural or mechanical component, designed to meet specific objectives, develops problems when the undesired effects of flow field have not been accounted for in the design. The developed mathematical containing fluid, or subjected to external flow. A simple criterion for the stability of the zero solution is presented. Author, Robert D.

The scoping process enables the design team to focus on lines with the perceived potential of experiencing high levels of long-term, low frequency, flow induced vibration, and is undertaken on the basis of easily identifiable flow conditions (such as intermittently flowing lines, flow-by-gravity lines, non-process critical . Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. For the values of reduced velocity below 0.7 first model is proposed, for the values above 0.7, the rest. The general principles are applicable under different flow conditions. In conclusion, two distinct mechanism were found to be responsible for flow induced vibration caused instabilities, (1) outside source controlled periodic excitation (such as vortex shedding) -- described by the first model and (2) fluid elastic forces -- described by second, third and fourth models. Get fast, free shipping with Amazon Prime. This book explains how and why such vibrations happen and provides hints and tips on how to avoid them in future plant design. In this manner, well-known theories on cylinders in cross-flow or well-executed solutions from the field of wind engineering--to name just two examples--may be useful in other systems or fields on which information is scarce. endobj Flow-induced vibration Robert D.
