Abstract: fluid-elastic instability of tube bundles is the main cause of vibration failure of heat exchangers. To establish more reasonable and reliable design guidelines for fluid-elastic instability of tube bundles subjected to two-phase cross flow, we investigated experimentally the effects of the flow conditions of the two-phase flow and the geometrical characteristics of the tube bundles on damping, vibration, and fluid-elastic instability. Moreover, we proposed recommended values of the instability constant based on the conductivity difference measurement (CDM) model and the classification of tube bundle arrangements. The reliability of these values was also verified. The results indicated that the damping ratio in the lift direction was smaller than that in the drag direction and fluid-elastic instability was more prone to occur. The order of stability of the four tube bundle arrangements from high to low was normal triangular, normal square, rotated square, and rotated triangular. Thus, to avoid fluid-elastic instability, the normal triangular tube bundle is recommended for large shell-and-tube heat exchangers subjected to two-phase cross flow. In addition, for normal square and normal triangular tube bundles, the recommended instability constant is 4.0. For rotated square and rotated triangular tube bundles, the recommended instability constant is 1.1 when the mass damping parameter is less than or equal to 0.54, otherwise the value is 1.5.

The paper considers the stability of a flexible cantilevered pipe which is hanging vertically with an internal flow into a large tank. This flow is forced out of the tank, upwards through a concentric rigid annulus around the pipe. Thus the internal and external flow velocities are in opposite directions and related by mass continuity. Parametric studies are carried out for 2 pipes with varying lengths exposed to the external flow and varying annular gaps. A theoretical model is developed, the analysis is rigorous and thorough, and the results and compared with experimental results. The nonlinear model is novel, the theoretical predictions generally agree very well with experiments, and the presentation is a model for clarity. This is excellent work.
