| Abstract: | A gas-kinetic model taking into account thermal and viscous effects was presented for nonlinear oscillations of gas in a piston-driven resonance tube in this paper.Development of gas oscillations in the closed tube and shock waves behaviors at resonance were numerically analyzed. The effects of frequency were studied on the resonant oscillating behaviors,pattern and pressure waveforms.The change of pressure ratio with frequency was also analyzed.The calculated results are well consistent with those from the... |
