Project summary

The aim of the project is to develop new theories and algorithms (or modify the ones created by the authors earlier), to generate systematic results (the numerical solutions), and to investigate into a set of currently challenging problems in gas/plasma and rigidbody motion mechanics, taking into account the governing parameters. This will continue the fundamental research whose results have been published earlier in three monographs and many scientific articles by A.N.Lyubimov, N.M.Tyurnnev, G. I.Khut and V.Yu.Velikodny. Two monographs have been translated in English and are popular among specialists in many countries.

These solutions are anticipated to completely describe flow patterns over simple (classical) bodies: hemisphere, cylinder, a body of revolution with a circular arc generatrix concave towards the flow, cone, a body composed of acute and truncated cones.

Also, flat shock waves and flows in convergent pergent (Laval) nozzles will be described. In some cases consideration will be given to models of inviscid and viscous gas, ideal gas with a viscous boundary layer, a gas with equilibrium and nonequilibrium physical and chemical reactions. Also obtained will be solutions outlining alienation areas on launching meteorological rockets.

The project will deal chiefly with the methods and computational algorithms based on the participants' numerical and experimental studies fulfilled earlier. Within the project the new results generated by the authors will be compared with the dispersed experimental data available and the solutions to academic problems, as well as with dispersed solutions available in literature from other authors. Particular attention would be paid to determining the solution accuracy.

Some foreign scientists (Prof. R. G. Roesner - Germany, Prof. F. Sabetta - Italy) have given their consent to participate in the work on the project and in consideration of its results.

The project should be categorized as conversion concerned. The project is anticipated to involve the authors' achievements in weapons aerodynamics/ballistics and implement these in alternative areas, i.e., to provide new scientific results in mechanics: gas/plasma dynamics, dynamics of gases with equilibrium and nonequilibrium physical and chemical processes, ballistics (for determining the alienation zones for meteorological rockets that make soundings in the upper atmosphere) and so forth.

The project would also be conducted to help settle the national and international conversion issues; in particular, aerodynamics of civil aircraft, space and rocket technologies, the technology operation safety, and environmental protection would be covered.

The outcome from the efforts is expected to be suitable to commercial utilization: the new methods, algorithms and numerically obtained results will be of certain importance.
