Effect of purge air on rotor endwall heat transfer of an axial turbine
Journal of the Global Power and Propulsion Society, 2017 In order to gain in cycle efficiency, turbine inlet temperatures tend to rise, posing the challenge for designers to cool components more effectively. Purge flow injection through the rim seal is regularly used in gas turbines to limit the ingestion of ...

Errors in Flow and Pressure Related to the Arterial Filter Purge Line
The Journal of ExtraCorporeal Technology, 1998 The purge line is a necessary component on arterial filters, although its presence may affect the amount of flow reaching the patient as well as the pump outlet pressure in the extracorporeal circuit. In-vitro and clinical studies conducted to investigate these effects with a commonly used purge line showed that at flows less than 1.5 L/min, rates for ...

Novel high-pressure turbine purge control features for increased stage efficiency
Journal of the Global Power and Propulsion Society, 2017 Rim seals throttle flow and have shown to impact the aerodynamic performance of gas turbines. The results of an experimental investigation of a rim seal exit geometry variation and its impact on the high-pressure turbine flow field are presented.

Effects of Purge-Flow Rate on Microbubble Capture in Radial Arterial-Line Filters. [PDF]
J Extra Corpor Technol, 2016 The process of microbubble filtration from blood is complex and highly dependent on the forces of flow and buoyancy. To protect the patient from air emboli, arterial-line filters commonly use a micropore screen, a large volume housing with purpose-built ...

Flow and Ingestion in a Turbine Disc Cavity under Rotationally-Dominated Conditions
International Journal of Turbomachinery, Propulsion and Power, 2021 An investigation of hot gas ingestion driven by the disc pumping effect in a chute seal was conducted at the Oxford Rotor Facility. Measurements of mean pressure, unsteady pressure and gas concentration have been logged and analysed under different ...
