Abstract:The rim seal is used to prevent the mainstream ingestion to the gap between the turbine vane and blade. In this research, the dolphin lip with a hook configuration and a large seal cavity with hook structures are designed based on the high-pressure turbine datum single shark lip rim seal configuration. Sealing effect and flow field parameters are measured by the experiment method, and numerical simulation is used to supplement the mechanism. For three configurations, the effect of leakage slot vortex on seal e… Show more
