Flow-induced vibration in heat exchangers

WebPage 54 of 105 o The lower velocity limit is desired to limit fouling, the higher velocity is limited to avoid erosion–corrosion on the tube-side, and Impingement attack and flow-induced vibration (FIV) on the shell side. o When sand, silt, and particulates are present, the velocity is kept high enough to prevent settling down. WebThis results in a split of the flow into either half of the shell with lower velocities and makes it possible to reduce the unsupported tube span length while keeping below a given allowable pressure drop. Tests were performed as a part of a systematic study of water flow-induced vibration in industrial-size heat exchangers.
