Документ Влияние нестационарности процесса теплопроводности на термическое сопротивление тепловой изоляции(НТУ "ХПИ", 2004) Капинос, Василий Максимович; Пустовалов, Владимир Николаевич; Мезерная, Мария ВитальевнаFor the transient conduction predictions the relations which describe convective heat exchange are used in the same form as for the steady-state conduction, which could not be always justified. In this connection the approximate solution of the transient conduction problem for an unlimited plate was considered with the replacement of its thermal resistance by the boundary conditions of the third kind. It is shown that the conventional heat transfer coefficient on the insulated plate in the form of the ratio of.Документ Распределение температуры в трубном пучке при поперечном обтекании(ru, 2004) Капинос, Василий Максимович; Пустовалов, Владимир Николаевич; Смородская, Инна ВасильевнаAt the cross-flow in a tube bundle in consequence of the gas temperature drop there is the different temperature of the tube walls. Because of that different heat deformations and stresses of the tubes arises, which can result in the failure of the tubes-plate juncture. The approximate method of the temperature distribution in a tube bundle is proposed.Документ Полуэмперическое уравнение для определения степени реактивности турбинной ступени(НТУ "ХПИ", 2004) Капинос, Василий Максимович; Навроцкий, В. В.; Смородская, Инна Васильевна; Марченко, Н. Д.An approximate equation for the definition of a stage reaction degree is presented. The equation can be used for heat calculation of a blading by parameters after a last stage.Документ О повышении экономичности паровых турбин с противодавлением(НТУ "ХПИ", 2004) Капинос, Василий Максимович; Навроцкий, В. В.; Михайлова, Ирина Александровна; Михайленко, Т. И.The question on use of steam turbines stages with the reduced reactions degree gradient is considered with the purpose of efficiency increase due to reduction the losses connected to leakings of environment through overbandage backlashes in flowing parts of turbines with rather short blades.
