1. Specification of Dorsal and Intermediate Telencephalic Character
Sammanfattning : The telencephalon is the most highly evolved region of the vertebrate central nervous system (CNS). The major structures of the telencephalon - the cortex and basal ganglia – derive from the dorsally positioned pallium and the ventrally positioned subpallium, respectively. LÄS MER
2. Aerothermal Study of Intermediate Turbine Ducts
Sammanfattning : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. LÄS MER
3. Experimental investigation of the flow field in an aggressive intermediate turbine duct
Sammanfattning : Intermediate turbine ducts are used for connecting thehigh-pressure turbine to the low-pressure turbine in turbofan engines. In order to meet the demands for more efficient and environmentally friendly jet engines, future intermediate turbine ducts need to have larger radial off-sets without increasing their length.

4. Experimental Investigation of the Aerodynamics and Heat Transfer in an Intermediate Turbine Duct
Sammanfattning : In today’s aero engines with large bypass ratios, the difference in diameter between the high pressure turbine and the downstream turbine, being either an intermediate or low pressure turbine, is large. There is also scope to further increase it, in order to increase the efficiency of the downstream turbine and enabling use of larger diameter fans. LÄS MER
5. Aerodynamics of an Aeroengine Intermediate Compressor Duct: Effects from an Integrated Bleed System
Sammanfattning : With the successful development of high-bypass-ratio turbofan engines, major aerodynamic components have been optimized and continuous efficiency improvements are getting harder to maintain. Therefore, to meet the requirements of lower emission of greenhouse gases, auxiliary modules such as intermediate ducts are receiving increasing interest. LÄS MER
