报告摘要:This work originates from phenomena and engineering problems occuring in the intermediate duct between the high pressure turbine and low pressure turbine in an aircraft engine. So for instance obstacles and surface enlargement (like ribs) as well as impinging jets may occur. In addition a so-called pocket cavity exists between the low pressure turbine exit and the outlet guide vane. The present talk highlights experimental and computational investigations of these phenomena with real world relevance.
