• This animation shows a perspective view of time development of turbulent vortex structures extracted by the formula used in Ref.[1].
• Many turbulent vortex structures are generated in the turbulent flow, and at some places, these structures interact with the gas-liquid interface.
• Time-development of fluid velocity mapping and vortex structures in an x-z plane is also animated in this, but the mapping is difficult to distinguish in this animation.
• Animation 3 focuses on the dynamics of turbulent vortex structures.
