FLOW-INDUCED VIBRATION IN SHELL-AND-TUBE HEAT EXCHANGERS WITH DOUBLE-SEGMENTAL BAFFLES
Аннотация
One of the techniques used by designers of shell-and-tube heat exchangers when they encounter a potential flow-induced vibration problem is to shift from a tube bundle with segmental baffles to one with double-segmental baffles. This results in a split of the flow into either half of the shell with lower velocities and the possibility to reduce the unsupported tube span length while keeping below a given allowable pressure drop. The tests were performed as a part of a systematic study of water flow-induced vibration in industrial-sized heat exchangers. Results for nine different double-segmental baffled bundle configurations are presented. Comparison of results with those for similar segmental baffled bundles shows that higher flows can be tolerated without developing damaging flow-induced vibration.
