Increasing the amount of thermal energy produced in a cogeneration unit on the base of internal combustion engine
(ТОВ "Планета-Прінт", 2021) Pylyov, V. V.; Pylyova, T. K.
Methodological instructions to calculation assignments "Thermodynamic and heat transfer processes" of the course "Theoretical Fundamentals of Heat Engineering"
(2023) Pylyov, V. V.
Principles ruling thermodynamic and heat transfer processes are important to understand for specialists working in all fields of knowledge related to designing and operation of devices and facilities for generation, conversion and transfer of energy. The mandatory assignments of the heat engineering course include three problems: – finding heat energy consumed by an ideal gas mixture, while it is being heated isochorically and isobarically, – calculating the thermodynamic parameters of states of an ideal gas during a cyclic process, as well as a work of the gas expansion, the thermal efficiency of the cycle, – calculating intensity of heat transfer in processes of forced and natural convection using criterial equations, solving the system of heat transfer and energy conservation equations. These methodological instructions contain tasks and methods of solving the assignments. Assignments solutions are expected to be given in handwritten form, done legible, and labeled with the student’s name, group and variant. Which variant of the task to solve is distributed by the lecturer. Calculated values must be presented with corresponding units of measurement permitted by International System of Units. The plots in solutions must be drawn keeping scale, their axes designated with titles, units and value labels near the tick marks. The works failing to meet said requirements are not accepted to be checked. After an assignment solution having been checked, the lecturer may ask additional theoretical questions related to the assignment topic to determine an appropriate mark. Self-check questions for preliminary making-ready for it are listed after the solving methods.
Methodological instructions to the laboratory work "Estimation of Thermal Conductivity of Heat Insulation of a Pipeline"
(2021) Pylyov, V. V.; Peresyolkov, O. R.
The intensity of conduction, which is a mode of heat transfer innate to solid bodies, is determined by the temperature gradient and the value of the thermal conductivity. The latter is a thermophysical characteristic of the substance, which in the general case depends on temperature and is usually found experimentally. The goal of the laboratory work is deepening knowledge of the theory of thermal conduction, obtaining the skills of carrying out experimental work to determine the thermal conductivity of materials. It is an important part of training of students regarding heat engineering.
Methodological instructions to the laboratory work "Analysis of the Process of Forced Heat Convection in the Tube Bundle"
(2021) Pylyov, V. V.; Peresyolkov, O. R.
Acquiring an ability to solve problems regarding forced convection is an important part of studying the discipline "Theoretical Fundamentals of Heat Engineering", as far it is the most abundant mode of heat transfer in all kinds of enginery, power plants, heat exchangers, heat-using devices and facilities. An accepted method of solving of such problems in simplified and generalized form provides for usage of similarity theory. Examination of the process of heat emission of a cylindrical tube in an air flow, and more complicated case of heat emission of a tube bundle, are convenient way to improve knowledge of criterial equation usage and gaining skills of their composing on a base of experimental data. Hence, the goal of the laboratory work is upgrading knowledge of forced convection, becoming familiar with methods of related experimental investigation and criterial equation set-up.
