  "abstract": "<p>The HZDR multiphase addon contains additional code for the open-source CFD software OpenFOAM, released by <a href=\"\\\">The OpenFOAM Foundation</a>. The developments are dedicated to the numerical simulation of multiphase flows, in particular to the multi-field two-fluid model (Euler-Euler method). Within the OpenFOAM library the multiphaseEulerFoam framework is used for this type of simulation. The addon contains a modified multiphaseEulerFoam named <em>HZDRmultiphaseEulerFoam</em> with the full support of the HZDR baseline model set for polydisperse bubbly flows according to Liao et al. (<a href=\"\\\">Chem Eng Sci, 2019, Vol. 202, 55-69</a>). In addition a solver dedicated to a hybrid modelling approach (dispersed and resolved interfaces, Meller et al., <a href=\"\\\">Int J Numer Meth Fluids. 2020, 1-26</a>) named <em>cipsaMultiphaseEulerFoam</em> is provided with the addon. This solver has an interface to the multiphaseEulerFoam framework and utilizes all available interfacial models of it.</p>\n\n<p><strong>General enhancements</strong></p>\n\n<ul>\n\t<li>modified turbulent wall functions of Menter according to Rzehak and Kriebitzsch (<a href=\"\\\">Int J Multiphase Flow, 2015, Vol. 68, 135-152</a>)</li>\n\t<li>dynamic time step adjustment via PID controller</li>\n</ul>\n\n<p><strong>HZDRmultiphaseEulerFoam</strong></p>\n\n<ul>\n\t<li>bubble induced turbulence model of Ma et al.
