Assessing passive scalar dynamics in bubble-induced turbulence using direct numerical simulations
By using direct numerical simulations (DNS) of bubbly flows with passive scalars, we show a transition in the scalar spectra from a k-5/3 to a k-3 scaling with the wavenumber k, in contrast with those of single-phase isotropic turbulence. For cases with a mean scalar gradient in the horizontal direc...
