Документ Анализ теплообмена при струйном охлаждении входной кромки лопатки газовой турбины(НТУ "ХПИ", 2009) Тарасов, Александр Иванович; Долгов, А. И.The numeral analysis of the flow and heat transfer under jet cooling in area of leading edge of the gas turbine blade is studied. The average heat transfer coefficients are calculated for the leading edge surface for the different flow regimes, jets, and fins on the wall. Basing on these data, the known heat transfer equations were analyzed. One of the equations was approved for using in the nozzle vanes or blades cooling system calculationsДокумент Оценка эффективности работы ЦНД турбины Т-250/300-23,5 Харьковской ТЭЦ-5(НТУ "ХПИ", 2009) Слабченко, Олег Николаевич; Зайцев, М. В.; Козлоков, А. Ю.; Золотухин, А. Д.It was proposed to carry out an estimation of the steam turbines flow paths efficiency for the low pressure cylinder in general and particularly for the low pressure cylinder of the T-250/300-23,5 steam turbine taking into account inherent operation conditions. Basing on such estimation it is possible to make recommendations for flow path modernization. Efficiency estimation for the each modernized variant should be developed basing on rate of the electrical energy generation. The rate can be determined by using the integrated characteristics of the turbine stages, i.e. mass flow rate, heat drop, performance factor in varying duty that were obtained as experimentally as well in calculations.
