Abstract: The elastic thermal stresses in a welded transition between two pipes of the same size but different alloys are explored. A stress-free temperature is postulated and the stress due to a uniform ...

Abstract: An analytical and experimental investigation has been made of the wear of a heat exchanger tube vibrating against a tube support. The purpose of this investigation is to develop a predictive ...

Abstract: Conceptual and empirical models are developed for the fretting wear of heat exchanger tubes. The models based on the experimental data of Part I of this series and on the concept that fretting ...

Abstract: The results of a series of measurements made on the fretting wear of heat exchanger tubes and support plates at room temperature in a nitrogen/air atmosphere are presented. The fretting wear ...

Abstract: Fatigue is produced by the sum of randomly phased sine waves. Fatigue damage during this non-Gaussian, finite random process is a function of the noise bandwidth, the fatigue slope, mean stress, ...

Abstract: The results of a series of over 700 measurements of the tube damping and natural frequency of heat exchanger tubes are presented. The damping and frequency measurements of the loosely held ...

Abstract: Models are developed for the fluid force coefficients that determine the onset of whirling of tube rows and tube arrays. A control volume momentum analysis is employed. The results are in ...

Abstract: An analytical model for flow-induced vibration of a tube row in a cross flow is formulated. A criterion for the onset of instability is developed. The tubes are modeled with different stiffnesses ...
