RISExperimental Measurements of Ingestion Through Turbine Rim Seals—Part I: Externally Induced Ingress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a new research facility which experimentally models hot gas ingestion into the wheelspace of an axial turbine stage. Measurements of the CO2 gas concentration in the rimseal region and inside the cavity ...
Experimental Measurements of Ingestion Through Turbine Rim Seals—Part II: Rotationally Induced Ingress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Part I of this twopart paper presented experimental results for externallyinduced (EI) ingress, where the ingestion of hot gas through the rim seal into the wheelspace of a gas turbine is controlled by the circumferential ...
Experimental Measurements of Ingestion Through Turbine Rim Seals—Part III: Single and Double Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes experimental results from a research facility, which experimentally models hot gas ingress into the wheelspace of an axial turbine stage. Measurements of CO2 gas concentration in the rimseal region and ...
Flow Instabilities in Gas Turbine Chute Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ingress of hot annulus gas into stator–rotor cavities is an important topic to engine designers. Rim-seals reduce the pressurized purge required to protect highly stressed components. This paper describes an experimental ...
