【 摘 要 】

The principles of physical and chemical processes modeling in a column spray-emulsion reactor in the form of dissipative structures are considered, which simplifies greatly the modeling. Comparison of two fundamentally different numerical methods of flow modeling is presented: Smooth Particle Hydrodynamics (SPH) method and method of Adaptive Mesh Refinement (AMR). The advantage of SPH method over the AMR grid methods is the high resolution at a constant number of particles. To solve the problem of simulation, a method similar to the method of smoothed Lagrangian particles was chosen. However, in the problem the mechanisms of interaction between particles, slag, metal, and also particle propagation are simulated. The isolation of dissipative structures made it possible to sharply reduce the dimension of the problem, since at the next higher level in this case, information is used only about the input and output parameters of this structure, complex interactions are closed within the dissipative structure. For the modeling the object-oriented programming language Action Scipt 3.0 was used, which allows the motion, the interaction of particles in a gravity separator to be visualized and animated in real time.
