By William K. Mechanics of Flow-Induced Sound and Vibration, Volume 2: Complex Flow-Structure Interactions, Second Edition , enables readers to fully understand flow-induced vibration and sound, unifying the disciplines of fluid dynamics, structural dynamics, vibration, acoustics, and statistics in order to classify and examine each of the leading sources of vibration and sound induced by various types of fluid motion. Starting from classical theories of aeroacoustics and hydroacoustics, a formalism of integral solutions valid for sources near boundaries is developed and then broadened to address different source types, including hydrodynamically induced cavitation and bubble noise, turbulent wall-pressure fluctuations, pipe and duct systems, lifting surface flow noise and vibration, and noise from rotating machinery.

Mechanics of Flow-Induced Sound and Vibration, Volume 2: Complex Flow-Structure Interactions

It seems that you're in Germany. We have a dedicated site for Germany. Editors: Ciappi , E. Flow induced vibration and noise FIVN remains a critical research topic. Even after over 50 years of intensive research, accurate and cost-effective FIVN simulation and measurement techniques remain elusive.

This book gathers the latest research from some of the most prominent experts in the field. It describes methods for characterizing wall pressure fluctuations, including subsonic and supersonic turbulent boundary layer flows over smooth and rough surfaces using computational methods like Large Eddy Simulation; for inferring wall pressure fluctuations using inverse techniques based on panel vibrations or holographic pressure sensor arrays; for calculating the resulting structural vibrations and radiated sound using traditional finite element methods, as well as advanced methods like Energy Finite Elements; for using scaling approaches to universally collapse flow-excited vibration and noise spectra; and for computing time histories of structural response, including alternating stresses.

The book offers a valuable reference guide for all those working in the area of flow-induced vibration and noise.

A hybrid numerical method was used to calculate the flow-induced noise and vibration of the centrifugal pump in the paper. The unsteady flows inside the centrifugal pumps with different blade outlet angles were simulated firstly. The unsteady pressure on the inner surface of the volute and the unsteady force applied on the impeller were analyzed. Then the vibration of the volute and sound field were calculated based on an acoustic-vibro-coupling method.

Flow-Induced Vibration of Power and Process Plant Components: A Practical Workbook is an indispensable, single source of information on the most common flow-induced vibration problems in power and process plant components. Based on the author's own experience that most errors in engineering analysis come from confusions in the units, the author begins with a short chapter on units and dimensions. He then provides step-by-step examples in dual US and SI units, leading to the final objective of design analysis, problem solving, diagnosis and trouble shooting in the following areas:.

Description

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 components in the flow, such as thermowells. An FIV study is recommended for new projects involving centrifugal compressors and other high flow gas systems. Speak to an expert. The potential of these phenomena to cause catastrophic failure to piping engineering systems and unacceptably high levels of environmental and occupational noise has motivated significant effort to understand and mitigate these problems. Flow disturbance or vortex shedding is caused by flow past:.

Мужчина выхватил оружие и выстрелил. Острая боль обожгла грудь Беккера и ударила в мозг. Пальцы у него онемели. Он упал.

 - Халохот улыбнулся.  - Может считать себя покойником. И он задвигал крошечными металлическими контактами на кончиках пальцев, стремясь как можно быстрее сообщить американским заказчикам хорошую новость. Скоро, подумал он, совсем. Как хищник, идущий по следам жертвы, Халохот отступил в заднюю часть собора, а оттуда пошел на сближение - прямо по центральному проходу.

За углом показалась смотровая площадка. Лестница, ведущая наверх, была пуста. Его жертва не приготовилась к отпору. Хотя, быть может, подумал Халохот, Беккер не видел, как он вошел в башню. Это означало, что на его, Халохота, стороне фактор внезапности, хотя вряд ли он в этом так уж нуждается, у него и так все козыри на руках.
