Badania eksperymentalne niestacjonarności pól przepływu w dwustopniowej turbinie akcyjnej
Języki publikacji
Abstrakty
The presented investigations were conducted on a modified impulse two-stage low-pressure model turbine with low-aspect ratio of airfoils. Real impulse turbine geometry has been used for both stages to investigate flow problems. A new supply system maintained very stable conditions at the inlet and flow-calming mesh-wiring and acoustic adaptation were built. These improvements allowed identification of different flow effects. A new measurement system was tested for investigations of influence of phenomena related, among others, to unsteady flow structures connected to vane indexing. It is of key importance for the turbine efficiency measurement.
Przedstawione badania zostały przeprowadzone na zmodyfikowanym stanowisku badawczym niskociśnieniowej dwustopniowej turbiny akcyjnej o małej rozpiętości łopatek. Przy projektowaniu geometrii turbiny do badań zagadnień przepływowych oparto się na geometrii rzeczywistej turbiny. Nowy system zasilania zapewnił bardzo stabilne warunki na wlocie, dodatkowo wstawiono siatki uspokajające oraz adaptację akustyczną. Ulepszenia te zapewniły identyfikację różnych efektów przepływowych. Przetestowano nowy system pomiarowy na potrzeby badań wpływu zjawisk związanych, między innymi, ze strukturami niestacjonarnymi powiązanymi ze zmianą położenia kierownic. Jest to kluczowe zagadnienie z punktu widzenia pomiarów sprawności turbiny.
