SOFTWARE COMPLEX FOR SOLVING THE DIFFERENT TASKS OF PHYSICAL GAS DYNAMICS

Abstract

This article is relevant due to the fact that The complexity of scientific problems solved by the methods of physical and mathematical modeling, the increasing requirements for the accuracy of their solution leads to an increase in the volume of data processed during the computational experiments. The aim of the work is to reduce the monetary and time costs for the work of scientific personnel which arise when using the weakly structured software that requires a large number of secondary activities not related to the activity on the performance of calculations, as well as providing the means of data exchange between the related research areas. This article discusses a computational algorithm and a set of software tools for modeling the fine structure of non-stationary multicomponent reactive gas flows and provides the structure of the complex, as well as the description of individual elements, and examples. A set of software tools for providing the numerical modeling of problems in the physical gas dynamics, including the graphic and information components supporting the resource-intensive stages of computational experiments is described. The complex of software tools consists of a graphical shell of control elements of the system; database of thermodynamic properties of substances and kinetic mechanisms, and the graphical interface for controlling it; module visualization of the results of solving computational problems; software components of the automated preparation of input data for the problem of modeling unsteady flows of the reacting gas. The developed set of programs can be used to solve the problems of the reacting gas dynamics, which are of practical importance, as well as the illustrator of training courses in the physical gas dynamics.
