Języki publikacji
Abstrakty
Celem pracy było trójwymiarowe numeryczne zobrazowanie zjawisk przepływowych w 1.5-stopniowej turbinie modelowej Instytutu Napędów Odrzutowych i Maszyn Przepływowych w Nadreńsko-Westfalskiej Wyższej Szkole Technicznej (IST RWTH Aachen) w Akwizgranie (Niemcy). Do badań wykorzystano udoskonaloną wersję kodu obliczeniowego Panta Rhei, stworzonego przez niemiecki Instytut, a uzyskane wyniki obliczeń porównano z pomiarami eksperymentalnymi.
The object of this study was an investigation of flow phenomena in a cold air turbine built at the Institute of Jet Propulsion and Turbomachinery at Aachen Technical University (IST RWTH Aachen, Germany). The said turbine was studied previously both experimentally and numerically with the IST's flow solver called Panta Rhei. Since that time certain improvements, computational-wise, were implemented in the code. In order to test them, new simulation runs were conducted.
