Ingress is the penetration of hot mainstream fluid into the cavity formed between the turbine
disk (rotor) and its adjacent casing (stator). Gas turbine engine designers use rim-seals fitted …

为探究涡轮轮缘密封的精细化设计, 在径向轮缘密封结构的基础上引入一种高径位供气孔结构并
将高位孔作为主要的封严气路, 采用经实验验证的非定常雷诺平均(URANS) 数值方法 …

Rim seal structures and sealing flows are essential in aero engines for preventing hot gas
ingestion from mainstream to turbine disk cavities. A novel design method of rim sealing flow …

Hot gas ingestion refers to the phenomenon of mainstream hot gas flowing into the space
cavity of a turbine wheel. Previous studies have found that mainstream annulus pressure …

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 …

Ingress is the ingestion of the hot gases from the main flow-path of a gas turbine engine into
the cavity (wheel-space) formed between the rotor disc and the stationary components. A …
