Summary:Fluid resonance within narrow gaps in multiple-box systems with sharp and round inlet configurations are investigated by using the potential flow and viscous fluid flow models in the OpenFOAM® package. Evident discrepancy between two numerical models can be observed for sharp inlet configurations. In addition to the dramatical decrease of resonant amplitude in narrow gaps, some peak values at the higher resonant frequencies predicted by the potential flow model even disappear in the viscous fluid flow results. The decreased normalized resonant amplitudes with the increase of incident wave amplitude can be observed for sharp inlet configurations. However, the hydrodynamic behaviors of multiple-box system with round inlet configurations between potential flow and viscous fluid flow models are quite similar with each other. The normalized resonant amplitudes are nearly independent of incident wave amplitudes for multiple-box systems with round inlet configurations. This implies that the energy dissipation associated with fluid viscosity and flow rotation plays an important role in the gap resonance for sharp inlet configurations; while it is insignificant for round inlet configurations.
