Abstract: In the modern multishaft gas turbine engines, orifice is an important throttling element, and the discharge coefficient of rotating orifices may vary considerably depending on the operating conditions, the geometry, and ...

Abstract: This paper developed a process for turbine tip clearance prediction and control considering performance degradation to address the contradiction between computational efficiency and computational accuracy. The developed ...

Abstract: The transient turbine tip clearance (δ) throughout the engine process is crucial to modern high-performance aero engines. However, there is still a lack of efficient and accurate transient prediction models of tip clearances ...

Abstract: Considering the complicated geometry in an active clearance control (ACC) system, the design of an improved cooling feed pipe with a covering plate for a high pressure ribbed turbine case was investigated. Numerical ...
