Euler’s multiphase model

For modeling of currents in which substances of various phases can mix up and do not form a free surface, in many cases it is possible to use both model of dispersion particles, and mixture model, and Euler s multiphase model. Additional criteria of sampling of appropriate model such are as follows (Menter, 2001). 

At very low relation yS, dispersion particles practically do not influence a stream of a bearing phase, and it is possible to use any of the listed models. At very high values P, dispersion particles strongly influence a stream of a bearing phase, and for appropriate modeling of a current it is necessary to use only Euler s multiphase model. At a mean p, for sampling of suitable model, it is necessary to compute Stokes number as it is presented more low.
