Abstract |
In shell and tube heat exchangers, tube bundles often fail due to the flow-induced vibrations. In
the current study, vibration response of the tubes, placed in the first and third row of the tube
bundle, has been examined having a normal triangular arrangement with pitch-to-diameter (P/D) ratio of 1.44. Each tube is tested for three different inside tube flow velocities of 0.85, 0.9 and 1 m/s and five shell side velocities ranging from 0.9 to 1.3 m/s with an increment of 0.1 m/s. This is the first experiment of its kind that offers insight into the tube vibration behavior made of glass material. The experimental analysis shows that tubes with internal flow vibrate with higher amplitudes than tubes without internal flow. Furthermore, the vibration amplitude of the tube tends to rise with increase in internal tube velocity even for the same shell side velocity. For the current range of shell and tube side velocity, with the internal flow from the tube, the hydrodynamic mass
of the tube i
