Liquid velocity fluctuations and energy spectra in three-dimensional buoyancy driven bubbly flows

We present a direct numerical simulation (DNS) study of pseudo-turbulence in buoyancy driven bubbly flows for a range of Reynolds (\(\Rey\)) and Atwood (\(\At\)) numbers. We study the probability distribution function of the horizontal and vertical liquid velocity fluctuations and find them to be in...
