Документ Анализ тепловой схемы и тепловых нагрузок Черниговской ТЭЦ в условиях снижения потребности в производственном паре и обоснование установки приключенной турбины, работающей от промышленных отборов других турбин(НТБ "ХПИ", 2011) Яковлев, А. И.; Кобцев, О. М.; Пугачева, Татьяна Николаевна; Панов, В. В.Urgent problem of Chernigovskaja HPP electrical power increasing was considered. Calculations and analysis of HPP turbine equipment operational modes were carried out. It is proposed to install the new turbine under the conditions of consumption decreasing of steam with industrial parameters. This new turbine will operate at the steam of 8–10 ata, which allows the increase of electrical power generating at HPP.Документ Термодинамічна оптимізація зразкових циклів деяких схем ГТУ та ПГУ(Національний технічний університет "Харківський політехнічний інститут", 2011) Волощук, Володимир АнатолійовичOn the base of mathematical modeling with the help of modern information technologies the article gives results of optimizing investigation of exemplary cycles of some schemes of gas turbine power plant and gas-steam combined power plant with the purpose of increasing inner efficiency.Документ Расчетно-экспериментальное определение теплофизических характеристик материалов при экстремальных тепловых воздействиях(НТУ "ХПИ", 2011) Веселовский, В. Б.; Беляева, В. В.; Грибанова, А. В.; Кириченко, Р. А.The mathematical model and computational methods of determination of bodies’ thermal physical parameters on the basis on experimental measurements by the laser flash method are presented. Solutions of unstationary heat conduction problem for constituent elements of construction with unified external boundary conditions and conditions of nonideal thermal contact were obtained. Results of computational xperiments are given.Документ Математичне моделювання дисипативного розігріву і визначення температурних полів елементів конструкцій при циклічному навантаженні(НТУ "ХПІ", 2011) Веселовський, В. Б.; Клим, В. Ю.; Берлов, О. В.; Підлісний, С. В.The technique of applied the method of successive intervals for definition temperature fields in elements of construction due to cyclic loading allows to take into account temperature dependences for thermomechanical properties of material and internal heat generation is obtainedДокумент Использование сбросного тепла в системе автономного теплоснабжения жилых зданий(НТУ "ХПИ", 2011) Титарь, С. С.; Климчук, А. А.It is offered to use warmly sewer waters and exhaust air in uniform systems of an independent heat supply of residential buildingsДокумент Влияние подогрева теплоносителя на теплоотдачу в каналах систем охлаждения(НТУ "ХПИ", 2011) Тарасов, Александр Иванович; Долгов, А. И.; Авдеева, Елена ПетровнаThe analysis of heat transfer in cooling channels in case of significant change of gas temperature was developed.It was noted that change of gas temperature affects on intensity of heat transfer along the channel. It was proposed improved equation for heat transfer coefficient that is valid for both air and water vapor.Документ Снижение неравномерности распределения напряжений в многоопорных хвостовых соединениях рабочих лопаток турбин(НТУ "ХПИ", 2011) Сухинин, В. П.; Фурсова, Т. Н.For the increase of equitability reactive efforts on the indents of tail connection the nospread functions of underlayments, providing indemnification of technological gaps due to deformations of crumpling, are offered. The construction of ultisupporting tail connection is improved by ationalization of general and local geometry of type.Документ Метод расчета течения в осерадиальных кольцевых каналах(НТУ "ХПИ", 2011) Субботович, Валерий Петрович; Юдин, Александр Юрьевич; Темченко, Сергей АлександровичIn this paper we consider the direct problem of axially symmetric flow of ideal gas in an annular axial-radial passage. Distributions of the mass flow rate of working fluid, total pressure, total specific volume, and tangential component of flow velocity over an inlet or outlet cross-section of the passage are taken as the initial data. The problem consists of independent flow calculation problems for any single cross-section of the passage. These independent problems can be solved both successively, one after another, and simultaneously.Документ Проблемы создания последних ступеней паровых турбин большой мощности(НТУ "ХПИ", 2011) Шубенко, А. Л.; Сухинин, В. П.; Бояршинов, А. Ю.The features of constructions of the last stage blades of steam turbines of high powere and basic results of scientific researches, allowing to choose the rational forms of elements of blades from the point of view of aerodynamics and durability are considered. The basic ways of further perfection of constructions are set.Документ Эксперементальное исследование тепломассопереноса в слое металлогидрида с теплопередающей матрицей(НТУ "ХПИ", 2011) Попок, А. В.; Ивановский, А. И.For the experimental study heat and mass transfer in a layer of metal hydride with the heat transfer matrix was designed and made the physical model – experimental metalhydride module (EMM). The temperature fields and spent characteristics were measured. It is shown the time dependence of hydrogen desorption from coolant temperature.
