On Some Heat Transfer Issues in An Intermediate Duct of An Aircraft Engine

Title:On Some Heat Transfer Issues in An Intermediate Duct of An Aircraft Engine

Reporter:Prof. Bengt Sunden

Time:Nov.11th  15:00-16:30

Place:Lecture Hall, Department of Thermal Engineering

Abstract: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.
