Characteristic boundary
WebSeveral characteristic boundary conditions suggested by Thompson, Watson-Myers and Hwang were tested and discussed to understand their physical meanings. Through the above tests, appropriate boundary conditions are selected and applied to simulate the pressure pulsation in the resonance tube.
