Abstract
This article describes a system of mathematical modeling of flows in controlled gas-jet systems and hydropneumatic devices having in its construction annular nozzles of different gas-dynamic types and geometrical configurations when flow of polyphase medium in flowing channel of annular nozzle. System of mathematical modeling is created by modular approach and includes support tools, functional content and databases. Functional content of the system presents a library of modules designed to solve a local problem of determining the characteristics of the annular nozzle. Included in the system function modules are designed to calculate the composition and thermodynamic characteristics of the products of combustion, profiling the annular nozzle, the calculation of mixed and supersonic flows, calculating the parameters of a turbulent boundary layer and flow separation region. Multifunctional system of mathematical modeling allows you to create multilevel computational systems that are used at various stages of the study the characteristics of the annular nozzle.
Keywords
