Abstract

The simulation model has been created during the mathematical description of the processes in the column reactor self-organizing jetemulsion unit; it is based on «first principles» and Monte Carlo method for statistical tests. The dispersed particles of the charge and reaction products, as well as all their possible transformations and interactions are considered as the first level of the research. The core of this model is presented by the streamline flowing process of the condensed particles by vertical gas flow. Wool-algorithm allows to simulate a large number of particles in a carrier gas stream, including taking into account the collisions of the particles and the exchange by vector values of pulses. The developed model allows to evaluate the dynamics of the separated streams of the metal, slag and gas, which makes it possible to close the loop of calculation cycle of substances in the unit. The algorithm and software implementation of the developed technique are developed. The conducted testing has shown performance of the algorithm and a satisfactory correlation of the final results of simulation modeling with the law of conservation of matter. Based on this technique, the simulation model (virtual reality) for a vertical gravitational separator (used for separation of the components of powdered materials) has been created. We also give an example application of this technique for separating components of a very fine dust in two very valuable marketable products from gas purification unit for manganese production. The task of creation of the technique for assessing the turbulent viscosity in a heterogeneous flow has been formulated on the basis of the conducted experiments on simulation and physical models.
