Abstract
The article provides an analysis of existing software systems that allow modeling hydrodynamic processes, as well as software systems whose functionality includes the calculation of ore processing and metallurgical technological schemes. Due to the fact that the software tools combining both considered functional areas were not found on the market, the software tool that simulates the process of gas-dynamic separation of granular materials by laminar gas flow, calculates the technical parameters of concentration and automatically selects the optimal process parameters in order to achieve maximum separation efficiency was developed. The work of the modules of the physic and mathematical model responsible for calculating the processes of particle acceleration in the acceleration channel, departure from it, movement in a gas jet, exit from the jet, free fall through the medium and collection in receiving containers, as well as modules responsible directly for calculating concentration indicators and calculating various values using two-dimensional matrices of input parameters is described. The developed software tool (a physic and mathematical model of gas dynamic separation), which is in the public domain, allows to study the patterns and features of each component of the gas dynamic separation process with various combinations of properties of the separated components and operating parameters, and also allows to automatically select the operating parameters of the gas dynamic separation of a new mixture of two components, ensuring maximum separation efficiency taking into account the Hancock-Luiken criterion adjusted by the Shekhirev criterion.
