A shell and tube heat exchanger design is not complete without a thorough vibration analysis. Flow induced vibration can occur depending on fluid flow conditions and the heat exchanger geometry (baffle placement, unsupported tube length, tube pitch, tube dimensions, etc.). The effects of vibration can lead to mechanical failures; tubes can collide with each other or against the shell wall, baffle damage can also occur.
The vibration analysis method used in AHED is the method recommended by TEMA: the Tubular Exchanger Manufacturers Association. TEMA has established and maintains a set of construction and design standards for heat exchangers, known as TEMA Standards and are accepted worldwide.
