Численные исследования ступеней МРТ с изменением положения сопел

Abstract

В выпускной квалификационной работе магистра изложено исследование нового метода повышения эффективности малорасходных турбин, путем изменения геометрии соплового аппарата, заключающейся в тангенциальном наклоне сопла. С помощью современных программных пакетов построено и исследовано три различных модели турбинной ступени. Рассчитаны такие характеристики ступеней, как: внутренний КПД, коэффициент скорости, коэффициент расхода и угол отклонения потока в косом срезе сопла. Сравнение итоговых результатов показывает положительное влияние предложенного метода на эффективность ступени.
