Heat-Exchanger Tube Vibration: A Technical Problem in the Application and Development of Heat-Recovery Systems

摘要

Waste-heat recovery systems require heat exchangers that can be economically built; and operated. However, economically optimized designs can lead to an increased potential for detrimental tube vibration. Tube vibration is thereby identified as a technical problem in the application and development of these systems. The dynamic behavior of an actual heat exchanger is reviewed. Tube-bundle dynamics are then discussed by considering the mechanical response of the tubes, vibration in statonary fluid, and flow excitation. Finally, design criteria and prediction methods are considered andresearch needs discussed. (ERA citation 08:026567)
