The Energy-Minimized Multiscale EMMS Model

There are thus three scales of interaction between the fluid and the particles  [Pg.570]

According to the above physical model, the following equations have been derived  [Pg.571]

The above six equations for continuity and force balance do not, however, afford a complete description of a heterogeneous particle-fluid system in which a dense phase and a dilute phase coexist. An additional constraint needs to be identified to account for the stability of the system. [Pg.572]

This constraint is to be provided through the concept of minimal energy. According to this concept, particles in a vertical flow system tend toward certain dynamic array which results in minimal energy. [Pg.572]

Consequently, modeling of a two-phase flow system is subject to both the constraints of the hydrodynamic equations and the constraint of minimizing N. Such modeling is a nonlinear optimization problem. Numerical solution on a computer of this mathematical system yields the eight parameters  [Pg.572]
