直交流中の密な格子配列管群からの渦放出と気柱共鳴現象との関係

Key Points

• This research aims to understand the relationship between vortex emissions and acoustic resonance in a lattice array of tubes.
• Experimental investigation of vortex emissions in a lattice array of tubes
• Utilization of a tube pitch ratio of 2.0 in both drag and lift directions
• Observation of flow behavior within the tube array
• Analysis of vortex stability and periodicity from the second row of tubes
• Flow within the lattice array is highly turbulent without acoustic resonance
• Vortex release from the second row of tubes shows weak periodicity
• Alternating and twin vortices are observed but lack stability
• Acoustic resonance is closely linked to the synchronization of vortices with the sound field
