6. CFD of Duct Acoustics for Turbocharger Applications
Sammanfattning : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. In this work the main focus is the turbocharger compressor and a discussion of turbocharger acoustics and earlier work within the area is presented, giving an insight into its sound generating mechanisms and the damping effect it has on pressure pulses, i.

7. Experimental Aerothermal Study of Internal Jet Engine Structures
Sammanfattning : In commercial aviation, efficiency improvements may be gained by aerodynamic optimisation of its structural components, such as the intermediate compressor duct (ICD) and the turbine rear structure (TRS). These components have frequently been overlooked in favour of compressor and turbine module optimisation. LÄS MER
8. Experimental Aerothermal Study on Internal Jet Engine Structures
Sammanfattning : For commercial aviation, one potential gain in efficiency can be found in the jet engine auxiliary modules, such as internal jet engine components. These components have historically largely been overlooked, prioritising units such as turbines or compressors. LÄS MER
9. A Linearized Navier-Stokes Equations Methodology for Aeroacoustic and Thermoacoustic Simulations
Sammanfattning : Aeroengine noise is one of the dominating noise sources in today’s aircraft. Reduction of the aeroengine noise is related to multiphysics phenomena, and that is subject to different mechanisms, e.g., the coupling between turbulence, flame and sound waves. LÄS MER
10. Design of Internal Cooling Passages: Investigation of Thermal Performance of Serpentine Passages
Sammanfattning : Gas turbines are used to convert thermal energy into mechanical energy. The thermal efficiency of the gas turbine is directly related to the turbine inlet temperature. LÄS MER
