RISStatistical and Theoretical Models of Ingestion Through Turbine Rim Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent papers, orifice models have been developed to calculate the amount of ingestion, or ingress, that occurs through gasturbine rim seals. These theoretical models can be used for externally induced (EI) ingress, ...
Experimental 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 ...
