Abstract A technology is proposed to improve the efficiency of heat devices operating on gas fuel. The technology is based on the use of a method of burning depleted ionized gas fuel in an electric field. Application of the method allows to reduce the formation of soot deposits and provides a more complete combustion of the gas. Increasing the efficiency of heating devices is achieved due to the formation of an electric field by including an ionizing radiation device in the structure of the gas stove. The energy of the ionizing radiation of the gas fuel provides the formation of Coulomb forces. Combustion intensifies, and convective heat exchange increases due to electroconvection. The design of the ionizing radiation device includes electrodes located at a distance from each other. Power is supplied from a voltage source. The electrodes are fixed using porcelain ring insulators. The proposed design solutions provide not only a decrease in gas fuel consumption, but also an increase in the flame temperature and the power of thermal radiation not only in the visible, infrared and ultraviolet ranges. Additional electrolysis of the fuel mixture, and the acceleration of its combustion rate is achieved due to ionization. The results of experimental studies to determine the parameters of the combustion processes of gas fuel (isobutane (CH3-CH(CH3)-CH3) – 72 %, butane (CH3-CH2– CH2-CH3) – 22 %, propane (C3H8) – 6 %) are presented. It was found that with a variable electric field strength for gas ionization, an increase in the temperature of the frying bed by 39%, heat transfer by 2 times, a decrease in carbon oxides by 31–36%, and a decrease in gas fuel consumption by 26% are achieved.

A study on the effect of high-frequency electric field on cereal seeds to increase seed germination and plant growth is presented. The study was conducted in the treatment of winter wheat seeds. High-voltage electric fields are one of the promising means of influencing crop seeds. One of the areas of use of high frequency high voltage electric fields is pre-sowing seed treatment, storage and processing. Experimental studies were conducted in the laboratory on a specially designed installation using a high-frequency high-voltage source. Processing doses have been established which make it practical to use a high-frequency, high-voltage electric field in electrotechnical winter wheat seed systems. Positive influence of high-frequency electric field on increase of sowing qualities and yielding properties of seeds is established. The optimal mode for determining the winter wheat field is the micro field, the mode is 16.8 kJ per 1 kg energy, the hour is 4 seconds, and the laboratory laboratory is 20% similar.

Over the decades, more attention has been paid to emissions from the means of transport and the use of different fuels and combustion fuels for the operation of internal combustion engines than on fuel consumption. This, in turn, enables research into products that are said to reduce fuel consumption. The report summarizes four studies of fuel-related innovation products. The studies covered by this report are conducted with diesel fuel and usually contain diesel fuel and three additives for it. Manufacturers of additives are based on already existing studies showing a 10-30% reduction in fuel consumption. Comparative experimental studies related to the use of commercially available diesel fuel with and without the use of additives have been performed in laboratory conditions. The studies were carried out on a stationary diesel engine СМД-17КН equipped with brake КИ1368В. Repeated results were recorded, but they did not confirm the significant positive effect of additives on specific fuel consumption. In some cases, the factors affecting errors in this type of research on the effectiveness of fuel additives for commercial purposes are considered. The reasons for the positive effects of such use of additives in certain engine operating modes are also clarified.

The enhancement of convective heat transfer by an electric field is but one aspect of the complex thermoelectric phenomena which arise from the interaction of fluid dynamic and electric fields. Our current knowledge of this area is limited to a very few experimental studies. There has been no formal analysis of the basic coupling modes of the Navier–Stokes and Maxwell equations which are developed in the absence of any appreciable magnetic fields. Convective flows in enclosures are particularly sensitive because the limited fluid volumes, recirculation, and generally low velocities allow the relatively weak electric body force to exert a significant influence. In this work, the modes by which the Navier–Stokes equations are coupled to Maxwell’s equations of electrodynamics are reviewed. The conditions governing the most significant coupling modes (Coulombic forces, Joule heating, permittivity gradients) are then derived within the context of a first-order theory of electrohydrodynamics. Situations in which these couplings may have a profound effect on the convective heat transfer rate are postulated. The result is an organized framework for controlling the heat transfer rate in enclosures.

Microgravity Conditions

In applications involving boiling in micro-devices or under microgravity conditions it is extremely desirable to enhance the heat transfer rate to increase the efficiency of these systems. Here, a possible mechanism is to increase the convective effects by application of an electric field on the bulk of the fluid. While the enhancement of heat and mass transfer by electric field has been known for decades, a fundamental understanding of the problem is still lacking, primarily due to the difficulties in conduct of experimental studies. Direct Numerical Simulations (DNS) opens up enormous possibilities for detailed understanding of EHD-enhanced film boiling. Such simulations can make it possible to capture the dynamics of the boiling flows. Here, we present a front tracking/finite difference algorithm, in conjunction with a leaky-dielectric electrohydrodynamic (EHD) model, to study EHD-enhanced film boiling on horizontal surfaces. According to this study, the bubble shape and its frequency of release are highly dependent on the dielectric properties of fluid, and electric field strength. Our results show an improvement of about 50% in the Nu number over that of the regular boiling in the range of parameters that are explored here.
