Beschreibung
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.
