ANALYSIS OF EXISTING HYPOTHESES OF MECHANISMS OF INFLUENCES OF ACOUSTIC AND MAGNETIC FIELDS ON TREATED LIQUID

abstract 1301706017 issue 130 pp. 253 – 267 30.06.2017 ru 172
The article compares various hypotheses that explain the mechanisms of the influence of the magnetic field with different characteristics on liquids, physico-chemical and biological systems. Physical effects that cause specific biological activity of water (magnetic treatment of water, production of thawed water, degassing, etc.) make water be metastable or non-equilibrium states. Water attracts the attention of researchers as a likely universal mediator in the transmission of electromagnetic field signals to the biological level. Water is involved in a variety of chemical and metabolic reactions, so the question about the ability to change the properties of water and solutions under the influence of fields of different nature: an electromagnetic field with different frequencies, with different combinations of field orientations (parallel constant and variable magnetic field, slope fields, rotating magnetic fields, magnetic fields close to zero and electric fields) arises. At the heart of existing methods for treating liquids lie methods that use the energy of the acoustic and magnetic fields, as well as complex methods of influencing the electromagnetic field in combination with thermal heating, pressure change, etc. The analysis of existing hypotheses about the mechanisms of the influences of fields of a different nature on the treated liquid makes it possible to put forward a hypothesis about the possibility of the joint influence of the acoustic and magnetic fields on the liquid by means of the acoustic and magnetic device

MATHEMATICAL EQUATIONS ANALYSIS OF ACOUSTIC AND ELECTROMAGNETIC FIELDS ARE CREATED BY ACOUSTIC MAGNETIC DEVICE AND DETERMINATION OF SIMILARITY CRITERIA FOR THE CREATION OF NEW CONSTRUCTIONS OF ACOUSTIC MAGNETIC DEVICES DESIGNED FOR USE IN HYDROPONIC SYSTEMS

abstract 1171603031 issue 117 pp. 500 – 527 31.03.2016 ru 227
Conditions in which the work of acoustic magnetic device proceeds are complicated because of the number of interconnections. Solving problems under such conditions analytically is difficult because of many variables and complexity of some dependencies. The article describes the conditions in which the work of acoustic magnetic device, designed for nonchemical treatment of hydroponic solution, takes place. The criteria, establishing the initial state of the chains, containing mutual inductance, are analyzed. The work establishes the criteria relating the physical parameters of the environment with the output parameters of the device. The similarity of conditions of heat transfer on the surface of the device is provided, and the relation of the scale of temperature and power lost when heating the ferrite and winding machine is determined. The criterion of the heat transfer process is defined. The criterion, determining the relation of the environment temperature to the thermal mode of the acoustic magnetic device, is defined. The criterion of the conditions at the boundaries of the system and cavitating liquid is determined. It is found, that the cavitation area appears in the technological volume of liquid at the work of acoustic magnetic device. The criterial equation for geometric parameters of different types and constructions of the acoustic magnetic device is defined. In accordance with the task based on the third theorem of similarity, the group of criteria that provides the similarity of the model to the proposed original by all existing indicators, is selected

THE RESULTS OF EXPERIMENTAL RESEARCH OF INFLUENCE OF ACOUSTIC AND MAGNETIC FIELD ON ELECTROCONDUCTIVITY AND PH VALUE OF HYDROPONIC SOLUTION

abstract 1101506035 issue 110 pp. 519 – 531 30.06.2015 ru 1123
The article deals with the results of research of acoustic and magnetic field influence on conductivity and pH value of hydroponic solution. For carrying out researches in this area the hypothesis of possibility of nutrient solution influence on ions by means of an acoustic and magnetic field is set up. A laboratory scale plant was constructed for a pilot study of the hypothesis. The solution was moved in the tube passing through a ferrite ring with winding. Thus, the solution was exposed to the influence of acoustic and magnetic field. The object of research was hydroponic solution of (NH4)2SO4; (NH4)2HPO4; K2SO4; Ca(NO3)2; MgSO4 in water having adjusted concentration and acidity. The solution was taken from the tank of laboratory scale plant by means of the pump, passed through the working area of the acoustic and magnetic device, filter, and then was poured into the tank, from which the sample for pH level changing was taken. The pH value was measured at the temperature of 22С by using electronic pH-meter KL-009(1)A. For control of instrument readings acidity was tested by universal test-paper. The initial pH value of solution made 5. As a result of acoustic and magnetic treatment of solution pH value of hydroponic solution increased from 6 to 6.9. The results show the possibility of pH value correction by small energy input
