Dispersed particles trajectory model , the interactions between the dispersed phase particles with the fluid , is often used to process the following ways : a fluid only consider the impact the relative dispersion of the particles , i.e., "one-way disaster bonding method ," which way flow field can be solved , and then solving the equations of motion of a solid particle , however, can only be used in this way for the dilute solid particle phase , otherwise will lead to large errors ; dispersed particles when the mass flow rate increases, would need to consider the interaction of the fluid phase and dispersed particles , namely, " Woe to close two-way approach " , which is a reflection of the increase of solid particle impact on fluid flow relative to the source term in the equation to get the flow field, but also on the flow field solid particle motion have an effect ; addition, if the nozzle is dense particles in the modeling phase ) , also taking into account the effect of a particle of a particle and a wall between the particles , known as " four-way disaster legal" , the method of construction mold and calculations are very complicated.

As the simulation has to conserve resources , repeatability, and can make it difficult to predict some experimental measurements of the amount and the discovery of new phenomena and other advantages , makes it occupies a very important position in the multiphase flow studies, in which aspects , scientists to solve specific multiphase flow problems , a variety of models and methods have been proposed . According to a variety of different methods rely on mathematical and physical principles , multiphase flow simulation methods can be grouped into three categories :

l) the classical continuum mechanics . Such methods study multiphase flow from the migration of macro-level , multi-phase flow based on an assumed Navier Stokes equations are controlled by the establishment of a continuous medium. Metal nozzle according to specific issues , the implementation of continuum mechanics model can be divided into : Euler -Euler method and Euler- Lagrange method. Existing homogeneous model , sub- model and the two- phase (multi ) fluid model belongs to the category of Euler -Euler method ; while particle dynamics model and particle trajectory models belong to the scope of Euler- Lagrange law .

2 ) molecular dynamics simulation . Such methods multiphase flow will be seen from the micro -level is a collection of a large number of discrete molecules , the motion characteristics of the fluid by the statistical average of the relevant characteristics of these discrete molecules to decide, these methods require large computer memory , is still not applied to the complex flow field. Direct Monte Carlo simulation method belongs to this approach .

3 ) mesoscopic simulation level. Such methods will be assumed to be continuous fluid medium , the control of equati
