Abstract

Three types of numerical models are employed in this work, including the conventional flow model, the viscous flow model and the modified potential flow model with damping coefficient, to investigate the gap resonance phenomena. Numerical simulations show that the conventional flow model over-predicts the wave amplitude around the resonant frequency; while the viscous flow model can agree well with experimental results. Moreover, the modified potential flow model with appropriate damping coefficient is validated that it can also obtain accurate results by comparing with experimental results and viscous results. For the purpose of accuracy and high efficiency, the modified potential flow model with damping coefficient is further used to investigate the gap resonance phenomena in four- and five-box systems. Numerical results show that the number of resonant frequencies increase with the increase of the boxes number, generally. Besides, resonant phenomena can only be observed at low-order resonant frequencies, the phenomena at highest-order resonant frequency always disappear.
