WebJun 17, 2024 · This paper presents experimental and computational results using a 1.5-stage test rig designed to investigate the effects of ingress through a double radial overlap rim-seal. The effect of the vanes and blades on ingress was investigated by a series of carefully controlled experiments: first, the position of the vane relative to the rim seal was … WebDec 14, 2024 · This paper proposes a new-designed rim seal configuration with sealing holes based on the conventional radial rim seal, and presents a numerical comparison of the sealing performance between the conventional sealing flow supply configuration and the new sealing flow supply configuration with holes at different sealing flow rates. The …
Flow instability effects related to purge through a gas turbine …
WebAug 30, 2024 · In high-pressure turbines, cool air is purged through rim seals at the periphery of wheel-spaces between the stator and rotor discs. The purge suppresses the ingress of hot gas from the annulus but superfluous use is inefficient. In this paper the interaction between the ingress, purge and mainstream flow is studied using unsteady … WebFeb 1, 2024 · 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 and computational study of … ghostwriting services rates

Webrotor blades of high pressure gas turbine stage design, and a chute seal at the periphery of the wheel-space between the rotor and the stator. The turbine receives the inlet flow from a screw compressor achieving a maximum pressure of 4 bar(a) at a nominal annular mass-flow rate of 4.7 kg/s.
