RISDesigning Piping Systems Against Acoustically Induced Structural Fatigue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Piping systems adapted for handling fluids such as steam and various process and hydrocarbon gases through a pressure-reducing device at high pressure and velocity conditions can produce severe ...
Fluid-Thermoacoustic Vibration of a Gas Turbine Recuperator Tubular Heat Exchanger System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low-frequency acoustic vibration of a vertical gas turbine recuperator during cold start-up is described. The vibration was identified as fluid-thermoacoustic instability driven by a modified ...
Eliminating Thermoacoustic Oscillations in Heat Exchanger and Steam Generator Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Systems comprised of hot and cold components containing gaseous fluids may be subject to thermoacoustic oscillations if the temperature gradient between the two components exceeds a critical ...
Unusual Acoustic Vibration of a Shell and Tube Process Heat Exchanger
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic vibration was experienced in a shell and tube process heat exchanger over a large range of operating conditions. Test and analysis results confirmed that the vibration was of an unusual ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Various methods for predicting and solving tube and acoustic vibration problems in heat exchangers in cross flow are presented: the use of stability diagrams comprising in-service experience of ...
Acoustically Induced Structural Fatigue of Piping Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Piping systems handling high-pressure and high-velocity steam and various process and hydrocarbon gases through a pressure-reducing device can produce severe acoustic vibration and metal fatigue ...
Suppression of Acoustic Waves in Steam Generator and Heat Exchanger Tube Banks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tube banks located in flow channels and exposed to crossflow have a low resistance to acoustic resonance and vibration in general. Such resistance can be increased substantially by placing ...
Effect of Tube-to-Tube Ties on Fluidelastic Instability of Tube Arrays Exposed to Crossflow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tube-to-tube ties and their arrangement within the tube array are shown to affect the onset of fluidelastic instability. The influence of tie arrangement for a single tube row and for an ...
Unusual Acoustic Vibration in Heat Exchanger and Steam Generator Tube Banks Possibly Caused by Fluid-Acoustic Instability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow channels of heat exchangers or steam generators containing tube arrays can be subject to acoustic vibration excited by flow of air, gas, or steam tranversely across the tubes. Such vibration ...
Prediction of Acoustic Vibration in Steam Generator and Heat Exchanger Tube Banks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Criteria are formulated for the development of acoustic vibration in transverse acoustic modes in steam generator tube banks, based on flow and acoustic parameters. Theoretical predictions are ...
