To study the flow-induced vibration characteristics of elastic tube bundles in heat exchanger
the shell-side flow-induced vibration responses of the elastic tube bundles are investigated based on the sequential solution method of bi-directional fluid-structure coupling with different tube bundle numbers and different tube bundle spacing. The split grid division strategy dramatically improves the accuracy
efficiency and flexibility of the grids. The step-by-step method of rough and accurate calculations can dramatically reduce the computing time and improve the computational efficiency. Numerical results show that vibrations of the elastic tube bundles induced by the shell-side fluid are mainly manifested as out-of-plane vibration
and the vibration uniformity is poor. The vibration amplitudes of the monitor points on the bigger stainless steel blocks are greatly influenced by the tube bundle spacing. In addition
the vibration frequencies of the monitor points on the smaller stainless steel blocks are greatly influenced by the tube bundle spacing
too. When the spacing between the elastic tube bundles is small
the interactions of the elastic tube bundles are strong. Furthermore
the increase of the number of the elastic tube bundle causes a decrease in the vibration uniformity of the elastic tube bundles.
