Abstract: |
The present thesis investigates the previous research on numerical simulation of self-excited vibration in pneumatic valves. Common research methods are classified into four types, including zero dimensional numerical simulation, three dimensional numerical simulation, the technique of zero-thickness virtual baffle with variable strake, numerical simulation of fluid-structure interaction by commercial software. Finally, suggestions on research process are provided. |
