#vibration Part I
Most heat exchangers operate successfully without vibration problems! While vibration does not mean that damage will occur, the importance of avoiding vibration problems at the design phase cannot be undermined; field repair of heat exchangers with vibration problems is more expensive and difficult than preventing problems at the design phase. Since, factors like increased size, flow rates and unstable conditions contribute to induced vibration, leading to mechanical failure, unacceptable flow fluctuations, exceeding noise levels and economic costs, it is important to avoid tube vibration when thermal design is being finalized.
There are four main reasons for tube bundle vibration induced by fluid in shell-and-tube heat exchanger, namely acoustical resonance, vortex shedding, fluid-elastic instability and turbulent buffeting.
In a series of upcoming posts, we are to provide you a brief discussion of various vibration mechanisms along with their corrective measures.
