Multiple ( two ) two-phase fluid dynamics of the basic methods for solving mathematical problems with the flow of the traditional model there are two categories : First, a mathematical model , obtained through a huge simplified analytical solution ; Second, the use of experimental results , using semi-empirical solution to the problem . With the rapid development of computer science , numerical simulation is increasingly becoming an important tool for two-phase study. Numerical simulation of two-phase current of each interlinked often handled in two ways : First, as a continuous phase , according to the continuity of the basic equations of the theory derived Euler type , known as Euler's method ; nozzle second is the regarded as a discontinuous phase of discrete , for each Lagrangian particle tracking conducted for the Lagrangian approach .

Currently in multiphase flow commonly used theoretical models are:

l) single- fluid model , the multiphase flow as a continuous medium mixture to a single treatment, this model assumes no difference in speed between phases , thus , leading to the calculation results with the experimental values ??have greater access , the mass flow rate decreases with increasing deviation increases.

Double (multiple ) fluid model , each phase were seen throughout the full continuum flow field , the mathematical description and processing methods using Euler's method , the characteristics of this model is a single-phase , respectively, to solve momentum and continuity equations equation, the force between the phases performed by the disaster phases together, however , is high and the calculation time required for the computer ;

Dispersed particles trajectory model , the fluid phase as a continuous medium , Dongguan industrial nozzle as discrete particulate phase processing medium , the particle phase , the force exerted by the various particles in a single analysis, the particles trajectories in the flow field and other parameters, it is clear that the use of the mathematical description and processing methods are Lagrangian method, which can be easily particle tracking of different sizes , to accommodate the complex flow field geometry particularly strong , its disadvantage is assumed that the particles have zero volume , namely that it is adapted to the case of particles than the thin nozzle , when the particle volume fraction is larger, its simulation results with the actual deviation from the larger , lower accuracy.
