| description | In practical engineering, pipeline vibration is often not caused by a single factor but by a combination of many factors. A fluid-structure coupling method is proposed in this paper and used to study the vibration of the compressor pipeline under the interaction of pipeline structure and airflow in it. The method is based on structured grids, so that the displacements of grid nodes can be calculated accurately at each time step. The results of transient calculation show that when the given inlet mass flow rate is constant and there is no other disturbance, the pressure fluctuation and the vibration of pipeline structure will occur by using fluid-structure coupling, and the vibration frequencies are consistent with the third- and fifth-order structural natural frequencies. Moreover, the higher the pressure in the pipe, the greater the fluid-structure coupling vibration. In addition, the fluid-structure coupling vibration not only occurs in the studied pipeline but also propagates to distant downstream pipeline. Comparing the above results with experimental results, it is found that the results of fluid-structure coupling calculation are in agreement with the actual situation, which shows that the method is reasonable and reliable and can be applied to engineering. |
