THEORY OF TURBULENCE AND SIMULATION OF TURBULENT TRANSPORT IN THE ATMOSPHERE PART 3

abstract 0591005014 issue 59 pp. 219 – 243 31.05.2010 ru 2136
The completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows over rough surface

TURBULENCE THEORY AND ROUGHNESS DENSITY EFFECT MODEL

abstract 0581004023 issue 58 pp. 348 – 382 28.04.2010 ru 2473
The model of the turbulent boundary layer over a rough surface is presented. The model is based on the special type of transformation of the Navier-Stokes equation. The turbulent boundary layer in this model is considered as a flow above the rough surface gener-ated by the viscous sublayer (the dynamic roughness effect). The roughness density effect on the shift of the mean velocity logarithmic profile has been estimated in the case of 2D and 3D roughness elements

THEORY AND CONSTANTS OF WALL TURBULENCE

abstract 0581004024 issue 58 pp. 383 – 394 28.04.2010 ru 2318
The completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows. The estimated mean velocity, temperature and impurity concentration profiles as well as the spectral characteristics of the streamwise velocity component are to be shown in a good agreement with the experimental data

INFORMATION-SYNERGISTIC ANALYSIS OF ELECTRONIC SYSTEMS OF ATOMS OF CHEMICAL ELEMENTS Part 1. Structured organization of electronic sys-tems in planes of subshell

abstract 0480904003 issue 48 pp. 24 – 44 30.04.2009 ru 4903
Analysis of electronic systems of atoms of chemical elements in planes of sub-shell with help synergetic information theory is conducted. It is found that peri-odic change of properties of chemical elements is ref-lection of periodic change of values R-functions of structured organization of electronic systems

CHAOS AND ORDER OF DISCRETE SYSTEMS IN LIGHT OF SYNERGETIC INFORMATION THEORY

abstract 0470903008 issue 47 pp. 96 – 129 31.03.2009 ru 11138
Estimation of chaos and order in structure of electronic systems of atoms, protein molecules, webs of spiders, poetic products is done with the help of synergetic information theory. Existence of statistical rule of structural organization in nature is expected. This rule directs evolution of discrete system towards balance of chaos and order.

SYNERGETIC INFORMATION THEORY Part 3. Information functions and Boltzmann entropy

abstract 0460902011 issue 46 pp. 165 – 174 27.02.2009 ru 8403
In the article it is shown that information-synergistic functions, in the face reflected information, additive negentropy and entro-py of reflection, they have direct interrelation with Boltzmann entropy.

SYNERGETIC INFORMATION THEORY Part 2. Reflection of discrete systems in planes of signs of their description

abstract 0450901012 issue 45 pp. 154 – 183 30.01.2009 ru 4174
Analysis of reflection of discrete system with final set of elements in planes of set of values of any sign is leaded. It is demonstrated that information reflected with system is divided on reflected and not reflected part and relevant information functions are got. Structured law of saving of sum of chaos and order is established and classification of discrete systems on their structural organization is given. Interrelation of synergetic and probabilistic information theories is shown. Law of information saving is established.

PROGNOSTIC EQUATIONS DIAMETERS AND THEIR MEAN SQUARE DEVIATIONS OF PINE FOREST STANDS OF KRASNOYARSK FOREST-STEPPE

abstract 0410807004 issue 41 pp. 47 – 55 15.09.2008 ru 3367
The aim of work is to get prognostic equations, taking into account the natural growth of pine forest stands of Krasnoyarsk forest-steppe along with influence of forestry arrangements and elemental factors. Dependences of weight average diameter and mean square deviation from age and plantation density were received in the article.

ABOUT POSSIBILITY AND USE OF MICROWAVE AND LASER RADIATIONS FOR INTENSIFICATION OF PLASMA CHEMICAL REACTIONS

abstract 0410807019 issue 41 pp. 313 – 325 15.09.2008 ru 3599
Further deviation of plasma components from thermodynamic balance in expense of free spins active carriers condition changes occurs when increasing the velocity of chemical processes in plasma by means of simultaneous overstrike of external magnetic field and irradiation of laser and microwave radiation flows.
