YANG-MILLS FIELD CAPACITOR

abstract 1121508145 issue 112 pp. 2020 – 2040 30.10.2015 ru 1069
The article presents a project of the capacitor in the Yang-Mills theory. Model capacitor represents the equipotential surfaces separated by a space. To describe the mechanism of condensation chromodynamics field used numerical models developed based on an average of the Yang-Mills theory. In the present study, we used eight-scalar component model that in the linear case is divided into two groups containing three or five fields respectively. In contrast to classical electrodynamics, a static model of the Yang-Mills is not divided into independent equations because of the nonlinearity of the model itself. However, in the case of a linear theory separation is possible. It is shown that in this particular case, the Yang-Mills theory is reduced to Poisson theory, which describes the electrostatic and magnetostatic phenomena. In the present work it is shown that in a certain region of the parameters of the capacitor of the Yang-Mills theory on the functional properties of the charge accumulation and retention of the field is similar to the capacitor of the electrostatic field or a magnet in magnetostatics. This means that in nature there are two types of charges, which are sources of macroscopic Yang-Mills field, which are similar to the properties of electric and magnetic charges in the Poisson theory. It is shown that in Yang-Mills only one type of charge may be associated with the distribution density of the substance, while another type of charge depends on the charge distribution of the first type. This allows us to provide an explanation for the lack of symmetry between electric and magnetic charges

YANG-MILLS FIELD AMPLIFIER

abstract 1111507077 issue 111 pp. 1200 – 1226 30.09.2015 ru 1388
The article presents a project of the Yang-Mills amplifier. Amplifier model is a multilayer spherical shell with increasing density towards the center. In the center of the amplifier is the core of high-density material. It is shown that in such a system, the amplitude of the Yang-Mills waves rises from the periphery to the center of several orders of magnitude. The role of the Yang-Mills field in the processes occurring in the nuclei of galaxies, stars and planets is discussed. The data modeling to strengthen the Yang-Mills field in the bowels of the planet, with an atomic explosion, and in some special devices such as the voltaic pile. To describe the mechanism of amplification chromodynamics field used as accurate results in Yang-Mills theory and numerical models developed based on an average and the exact equations as well. Among the exact solutions of the special role played by the centralsymmetric metric describing the contribution of the Yang-Mills field in the speed of recession of galaxies. Among the approximate numerical models can be noted the eight-scalar model we have developed for the simulation of non-linear color oscillations and chaos in the Yang-Mills theory. Earlier models were investigated spatio-temporal oscillations of the YangMills theory in the case of three and eight colors. The results of numerical simulation show that the nonlinear interaction does not lead to a spatial mixing of colors as it might be in the case of turbulent diffusion. Depending on the system parameters there is a suppression of the amplitude of the oscillations the first three by five colors or vice versa. The kinetic energy fluctuations or shared equally between the color components, or dominated by the kinetic energy of repressed groups of colors. In the present study, we found that amplification chromodynamic field leads to a sharp increase in the amplitude of the suppressed color, which can lead to an increase in entropy, excitation of nuclear reactions and decays particles

WHETHER THE SOCIO-ECONOMIC PHENOMENA OBEY SOME ANALOGS OR GENERALIZATIONS OF THE PRINCIPLE OF RELATIVITY BY GALILEO AND EINSTEIN AND THE THEOREM OF NOETHER AND CONSERVATION LAWS?

abstract 0911307014 issue 91 pp. 222 – 257 30.09.2013 ru 1627
This article proposes a generalized principle of relativity, similar to Galileo's principle of relativity Ein-stein, but for all kinds of real and virtual systems, not just the physical, hypothesis about his relationship with the theorem of Emmy Noether and laws of con-servation of energy, momentum and angular momen-tum in the socio-economic and psychological systems. On the basis of the information theory of time and information theory of value (E.V. Lutsenko, 1980), the conclusions about the non-uniformity of the course of time in social systems, inhomogeneity and anisotropy's of a bench economic space and violations of the laws of conservation of energy, momentum and angular momentum in social systems, and accordingly, of a failure to comply or only partial implementation for them the generalized principle of relativity have been made in the article

Warm, warmth and internal energy of a body

abstract 1111507038 issue 111 pp. 680 – 694 30.09.2015 ru 963
The article discusses the question of the concepts of heat and internal energy of a body. The analysis of these concepts in the historical aspect and the views of the author, based on the new photon theory of atomic structure were presented in this study. The analysis of the historical aspect of this question tells that the concepts of heat and internal energy of the body for a long time were associated with the concept of caloric, which can flow in the substance. The next step was the identification of the concept of heat with energy linked with the movement and work. In accordance with this, Clausius proved the equivalence of heat and work as the first principle of the theory of heat and introduced the concept of internal energy, which can be increased in two ways - making work on body, and summing heat to it. Thus, energy was the main uniting factor of work and heat. Then, the kinetic theory of heat, as the energy of motion of molecules, was developed by Maxwell and caloric model turned out to be a hindrance in the development of the theory of heat. In fact, the internal energy of the body is determined photons, rotating around charged particles in atoms in their orbitals. The series of photons are combined into a single photon orbital direction of rotation of the photons, which are different from each other. Thus, the body has an internal energy or internal heat. It is due to the energy of photons, orbiting electrons in the outer shell of each atom, as well as around the charged particles - electrons and protons in the nucleus of an atom. This internal energy may be increased by mechanical action on the body, leading to an increase in resulting oscillation frequency of photons around charged particles of atoms and the internal heat contained in the body can flow of the body with a higher concentration of heat to the body with a lower concentration of heat

VORTEX TURBULENT FLOWS IN ATMOSPHERES OF PLANETS AND ON THE SUN

abstract 1341710109 issue 134 pp. 1387 – 1411 29.12.2017 ru 382
In this work, we consider two types of vortex currents-cyclones and anticyclones in the Northern and Southern Hemispheres. Numerical modeling of turbulent flows of these types uses the model of the planetary boundary layer developed by the author. The purpose of the study is to test hypotheses about the influence of the Coriolis force on the formation of cyclones and anticyclones in the northern and southern latitudes. The first hypothesis on the direction of circulation in cyclones was verified in the case of axisymmetric radially converging and vertically rising turbulent flows with a natural Coriolis parameter and viscosity. From the obtained data of numerical experiments, it follows that the current in the northern latitudes circulates in a counter clockwise direction, and in the south - in a clockwise direction, in full accordance with the observational data. Thus, we have shown that a cyclonic flow is formed in a turbulent radially converging flow under the influence of the Coriolis force. The second hypothesis on the formation of anticyclones was verified in the case of radially divergent and vertically descending turbulent flows. Because of numerical experiments, it was established that in this case, the current in the northern latitudes circulates clockwise, and in the south - in a counter clockwise direction, which corresponds to observations for anticyclones. To test the effect of the cyclone (anticyclone) center velocity on circulation, a nonstationary 3D model of turbulent flow was developed. Within the framework of this model, flows in cyclones and anticyclones moving at a constant speed, as well as in shear flow, are studied. Some types of loop protuberances on the Sun are explained by the presence of a vortex turbulent flow starting in the bowels of the Sun and encompassing the chromosphere

TURBULENCE THEORY AND ROUGHNESS DENSITY EFFECT MODEL

abstract 0581004023 issue 58 pp. 348 – 382 28.04.2010 ru 2517
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
