- Spatiotemporal Structure of Density Destratification by a Bubble Plume
抄録
Fluid dynamic process of density destratification enabled by a bubble plume is investigated. General parametric dependence to global mixing is studied with numerical simulation coded by number density model of bubbly flow and then multiple experiments using dye visualization and ultrasonic velocity profiling (UVP) are carried out to find out the spatiotemporal structure of the two-phase flow emerging during destratification. The results show that intermittent convection driven in the near field of the bubble plume plays the primary role of the destratification. The intermittency is triggered by interaction between the near-field turbulence and the far-field wavy motion of bubble plume, which is clearly shown by the recurrence map and the power spectra of the velocity fluctuation measured by UVP.
