Project summary

The goal of the project lies in the development of new techniques and programs (codes) modeling 3D vortex flows in gases and plasma, as well as the graphic methods of processing the data from the obtained results; the adaptation of the mentioned programs for multiprocessing computers; the solution of the problems of modern astrophysics and inertial fusion. The noted techniques and programs can find use in the following areas:
— computer modeling of vortex flows in astrophysical objects;
— fusion research (ICF);
— Earth protection from the asteroids;
— supersonic streamline flow modeling for the objects of complex configuration.

Expected results

Development of the methods and algorithms, as well as the 3D codes, for the complex gas dynamic flows in Euler coordinates with adaptive local diminishing steps of nets.

Elaboration of the algorithms and programs aimed at calculation of complex gas dynamic flows in moving Euler coordinates. In order to describe the evolution of strongly deformed interfaces of the different media it would use the mixed cells and nonsrtuctured net of markers.

Creation of parallel algorithms for the solution of gas dynamic problems, including the heat transfer in plasma.

The elaboration of graphic programs aimed at the processing of the results from 3D calculation, and their presentation in the convenient form.

Study into the fundamental laws of the vortex flow formation and evolution under the presence of hydrodynamic instabilities.

The effect of the electron and radiation transfer on the development of hydrodynamic instabilities.

The present Project is based on the results obtained during the work on the ISTC Projects 029-94 and 177-96. One of the main results obtained from the work on the Projects is the formation of a professional team of specialists working in the field of physical-mathematical models, the creation of complicated numerical codes, including the multidimensional simulations and graphic processing of the data obtained. The weapon scientists take an active part in the work, and this one of the important goals put by the ISTC.
