turbulence-model-for-each-phase

+*solves a set of k and ε transport equations for each phase.
+*is appropriate choice when the turbulence transfer among the phases plays a dominant role.

+*Turbulence predictions are obtained from two long equations which both of that equations have two terms that must be approximated like these:
* Clq = 2,
* Cql = 2ηlq/(1+ηlq).
where: ηlq is the ratio of the characteristic particle relaxation time and the Lagrangian integral time scale of the phases q and l.

+*The turbulent viscosity defined as a equations.

Recomended for the thesis (1st priority), and use LAUNDER and SPALDING (1974), because so famous used by researchers like Lu and Howatrh (1996a, 1996b). Although we can use in simulation as 2nd priority,dispersed t. m. or mixture t. m. as the 3rd priority for these works.
