"Useful work of unsteady aerodynamic and hydrodynamic forces and moments arising from the flutter vibrations of objects in the flow of fluid"
A brief description of the problem, which is devoted to the report. Report SP Goncharenko is devoted to the management and maintenance of the appearance of oscillations such as flutter in the interaction with the working elements of the fluid flow, as well as converting the kinetic energy of the fluid flow into electrical energy through the use of the useful work of unsteady aerodynamic and hydrodynamic forces and moments (unsteady aerodynamics influences - UAI) arising from the self-excited oscillations of objects in the flow of the fluid.
Relevance of the theme of the report. The relevance of this report is not in doubt, as is shown both theoretically and practically possible not only to control the emergence and maintenance of self-oscillation type of flutter in the given parameters, but also the possibility of totally environmentally safe conversion of kinetic energy of the flow of water and air into electrical energy. Installed a new, previously unknown phenomenon of nature - getting useful work of unsteady aerodynamic and hydrodynamic forces and moments occurring in the stream of self-oscillations in the current environment objects. The author of the report to substantiate the mechanism of control unsteady aerodynamic and hydrodynamic processes showed that the phenomenon of self-oscillations is essential to obtain additional energy that occurs when converting the kinetic energy of the fluid flow into useful work by UAI. Patterns obtained by the author objectively exist in nature in the event of any fluid.
The most important aspects of which are disclosed in the report author. Author's work is a serious and current scientific work on the little-studied subject: "Useful work of unsteady aerodynamic and hydrodynamic forces and moments arising from the flutter vibrations of objects in the flow of fluid." The author began his presentation gives a detailed analysis of two seemingly different, phenomena: the economical movement of the dolphin in the nature and type of flutter phenomenon of self-oscillations in the art. Focusing on the similarity of the vibrational motions of the body and a single dolphin sufficiently flexible cylinder in a longitudinal flow of a fluid, the author proceeds to the theoretical basis of the conditions of flexural-torsional flutter and practical realization of this phenomenon in order to create a technical device to reproduce the kinematics of motion of a dolphin. Based on the analysis of theoretical studies of aeroelastic vibrations of the author of the report proposed the original theory of a possible summation UAI resulting from the implementation of certain conditions of interaction of oscillating working elements of the device with the flow of fluid from the normal component of the driving force of the stream. In addition to playing the kinematics of motion dolphin author of the report suggested the possibility of obtaining useful work related to the conversion of kinetic energy of the fluid flow into useful work by UAI.
To confirm this theory, the author of the report was designed and constructed laboratory apparatus, as well as the methodology of research on the aerodynamic stand. The research results of the laboratory setup, obtained on an aerodynamic stand, not only confirmed the theoretical assumptions of the author about the possibility of converting the kinetic energy of air flow into electrical energy by the sum of the driving force of the flow and UAI, but also led to the continued testing of the laboratory setup in the aquatic environment.
The method of mooring trials of the laboratory setup was used by the author of the report of the same standard method of mooring trials of the ordinary courts, which ruled out the probability of methodological errors in the tests. The test results of the laboratory setup, obtained in aqueous media, confirmed the test results obtained in air.
The criterion of truth of any theoretical assumptions is practice. That is why this report focuses on the use of significant effects obtained and naturally in the wild in practice. Based on experience gained from laboratory studies, the author of the report was designed and built an experimental industrial plant, which enabled a comprehensive study on the subject of useful work in NAV arising from the interaction of work items set in the mode of oscillation to the flow of fluid at the actual rates of air and water flows.
Past studies of the interaction of work items arising from the self-excited oscillations of objects in the flow of the fluid, let the author of the report conclude that the useful work of unsteady aerodynamic and hydrodynamic forces and moments (UAI) is an objective law. The author shows in detail the mechanism of management of these UAI, resulting in the phenomenon of self-excited oscillations of the "flutter" that occurs in uniform and in nonuniform flows is a prerequisite for more energy associated with the transformation of the kinetic energy of the fluid flow into useful work. Particularly important is the fact that this pattern is completely natural permeated the living creatures in nature itself, this law is eternal, like life itself, there is no matter of the mind and will of man, she appeared with the emergence of life and may disappear only with the complete disappearance of life.
Special attention is given an explanation of the author of the mechanism of movement of the fish, which allows the realization of living beings to obtain additional energy to move. Supported by all laws, studied and described in the works of the English scientist James Gray: laminar flow over the animal's body, the absence of a turbulent boundary layer, "extra" energy of motion. In the role of the mechanism responsible for the presence of a negative gradient of dynamic pressure along the animal's body, as well as for the production of "extra" energy of motion are the UAI, which control mechanism in living beings genetically incorporated.
The results of research carried out in water and air in different areas of technology, let the author of the report to conclude that these laws exist objectively in any fluid and can be used in the technique for converting the kinetic energy of the flow of any fluid into useful work.
As in nature, the possibility of using this source is limitless.
This report also attempts to understand the areas of possible practical use of an open event. The most realistic and there is no doubt an effective and completely environmentally safe use of the open events in the technique as:
- The interaction of wind turbine installation work items with a stream of air;
- Hydro workers in the interaction of elements of the unit with water streams, as rivers, streams, canals, tidal, offshore and ocean currents, waterfalls, sea surf. In this case, an alternative environmentally sound sources of efficient conversion of kinetic energy of water flow into electrical energy for humanity yet (except for hydro, involving the construction of dykes and dams);
- An engine for marine and river vessels.
Heard by the novelty of the work is different and conclusiveness of ideas.
After discussion, the discussion of the report, the seminar adopted the following conclusion.
1. Presented by the author of the report of numerous studies the phenomenon of self-oscillations of objects in the flow of fluid is quite reliable;
all the phenomena described by the author and are new priorities for modern science;
2. The basic gist of the report is shown that: good work of unsteady aerodynamic and hydrodynamic forces and moments occurring in the flow of flowing medium at flutter vibrations of objects is an objective law.
The work of its principal physical and practical innovation, in essence, is the discovery of new phenomena of nature, which makes a fundamental contribution to the development of aero-and hydrodynamic processes that occur during self-oscillations of objects in the flow of the current environment.
