Dynamic Characteristic Analysis of Fluid-filled Pipe under the Action of Fluctuating Pressure |
| |
| Abstract: | The flow field simulation of fluid-filled pipe was first researched by Fluent in this paper and the features of pressure changes of fluid-filled pipe was analysed under the influence of periodic velocity. Then, the model of only-way fluid-structure coupling was based on ANSYSWorkbench, and the characteristics of vibration mode was analysed under the effect of pressure fluctuating pressures and with different support interval of fluid-filled pipe. The study can be used as a reference for the design of engineering. |
