Beskrivelse
Modelling turbulence in bubbly fl ows that arise in the engineering
and environment is of great challenges for multiphase
Computational Fluid Dynamics. In the present book
various turbulence modelling approaches are investigated in
bubble columns and bubbly channel fl ows. The considered
approaches contain Scale Resolving Simulations and the traditional
Reynolds-averaged Navier-Stokes closure. The focus
is set on the representation of the so-called bubble-induced
turbulence in the modelling framework. A major chapter addresses
a complete route to construct such a model embedded
in Euler-Euler approach with the aid of Direct Numerical
Simulation data. This procedure is employed to propose an
improved model for bubble-induced turbulence.
