摘要：According to the multilayer high pressure turbine case applied in an active clearance control system, a typical compound cooling structure consisting of impingement with high ribs and embedded bolts was investigated. The effects of jet Reynolds number, the ratio of height of rib to jet hole's diameter on local and average heat transfer coefficients were experimentally studied. It was found that the heat transfer coefficients of target surface were improved with the increase of jet Reynolds number, while the growth rate slowed down. The highest average heat transfer coefficient was observed at the region near the exhaust channel when three rows of jet holes were used. The experimental results showed that the heat transfer coefficients on high rib surfaces were influenced by both the height of rib and impinging Reynolds number. Increasing the height of rib led to higher heat transfer coefficients, and this trend becomed more distinguished in large Reynolds cases. © 2017, Editorial Department of Journal of Aerospace Power.
