Description Description
Standard k-epsilon turbulence model Mixture k-epsilon turbulence model for two-phase gas-liquid systems
The basic structure of the model is based on:
\verbatim
"Modelling of dispersed bubble and droplet ow at high phase fractions"
A. Behzadi, R.I. Issa , H. Rusche,
Chemical Engineering Science (59) 2004 pp.759-770.
\endverbatim
but an effective density for the gas is used in the averaging and an
alternative model for bubble-generated turbulence from:
\verbatim
"The simulation of multidimensional multiphase flows",
Lahey R.T.,
Nucl. Eng. & Design
(235) 2005 pp.1043-1060.
\endverbatim
The default model coefficients correspond to the following: The default model coefficients correspond to the following:
