【 摘 要 】

The article describes a dissipative structure - gravity separator in the jet-emulsion reactor. The simulation model is based on "first principles" and the Monte Carlo method of statistical tests. Dispersed particles of the charge and reaction products, their possible transformations and variants of interactions are treated as the first level. The core of this model is the process flow of the condensed particles in the vertical gas flow. Taking into account the experience of simulation and the presented considerations the concept of turbulent viscosity for heterogeneous flow is defined, the task and the direction of further investigations are defined.
