Full textA thesis for Doctor of Technical degree, specialty 05.17.08 – process and equipments of chemical technology. – National Technical University "Kharkiv Polytechnic Institute" Ministry of Education and Science of Ukraine, Kharkiv, 2016. The thesis deals with the improvement of actual engineering science-technical problem: the development of the modern energy effective ecological technologies, the means of energy generation and consumption using the heat recuperation systems on the base of synergetic unity of hardware implementation of the processes and system approach. For that the methodological fundamentals and practical methods of increasing of fuel utilization efficiency in the gas-liquid apparatuses and in the fuel combustion units of chemical technology at the expense of heat processes intensification were developed. Looking for improvements in fuel efficiency and materials saving the new constructions of gas-liquid apparatuses and fuel combustion units were created. On this base the ecological and energy efficiency technological systems were synthesized. They confirm to the requirements of modern power engineering and they are acceptable for the chemical technology and the other industries, as well as for communal services and agriculture. The high-effective contact-module system was developed. It was equipped with the immersion combustion apparatuses with multiple phase inversion and oscillation modulating of contacted phases. The system can be used for heat supply of industrial and agricultural buildings, apartment houses without using boilers with heat utilization of combustion products, when heat rating of 200, 400, 600, 1000, 2000 kWt is assumed, depending a need for generated heat. The expenses for complex structures and buildings’ heating using the development are decreased by 2,5 – 2,8 times in comparison with the traditional means. Contact-module system has stood the government heat-ecological test, which confirmed its high efficiency, ecological compatibility, serviceability. Construction standard specifications for serial production in the different branches of economy were obtained. The developed and presented in the thesis apparatuses, technological processes and equipments were applied in chemistry, metallurgy, motor-car industries and in communal services in Ukraine and CIS countries.

Full textThesis for granting the Degree of Candidate of Technical sciences in speciality 05.05.16 – Hydraulic machines and hydropneumatic units. – National Technical University "Kharkiv Politechnic Institute", 2018. The dissertation is devoted to the solution of an important scientific and technical problem of increasing the efficiency of a submersible electric centrifugal pump when it operates on a real liquid, which is a mixture of viscous non-Newtonian fluid, water and gas by improving mathematical models. An analysis of the concepts of development of pumping plant in Ukraine is carried out. The methods of mathematical modeling of three-dimensional flows of a viscous real liquid and their advantages over physical experiments are described. Selected software package for numerical experiment in OpenFOAM submersible pump channels. A system of indeterminate and Navier-Stokes equations was used to simulate the flow of fluid in the flow section of the pump. For its closure a k-ε turbulence model was chosen. The influence of rheological properties of non-Newtonian fluids on the characteristics of a centrifugal pump is investigated. The mathematical model of the turbulent three-dimensional flow of the non-Newtonian fluid is given. For calculations, a model of the Herschel-Bulkley non-Newtonian fluid is chosen, which most accurately describes the behavior of liquids of this type. The dependencies for the recalculation of the characteristics of the pump during its operation on the real liquid have been improved. The approach and mathematical model for modeling the three-dimensional flow of a viscous gas-liquid mixture are determined and chosen, and features are shown in the calculations of this type of fluid in the OpenFOAM package. The ways of increasing the efficiency of submersible pumps by changing the flow part are considered. The rational angle of inclination of the initial edge is determined. The modified degree of the pump, protected by the Ukrainian patent, is offered for pumping a liquid with an increased gas content. The mathematical model of a compatible operation of a real well and a submersible centrifugal pump in the form of a package of applied programs is considered and improved. This made it possible to determine the basic physical characteristics of the liquid, depending on the thermodynamic conditions.
