Design of a Shell-Side Distributed Pulsating Flow Generator

It can be seen from the above statement that the ETB in the heat exchanger has the problem of uneven vibration of each row of ETBs. In this way, parts of the ETBs are prone to fatigue damage, and parts of the ETBs heat transfer effect are poor, affecting the service life and heat transfer efficiency of the heat exchanger. Therefore, the research of pulsating flow generators which can reasonably induce and control the vibration of each ETB in heat exchanger has gradually attracted the attention of academic community.
