1. Aerodynamic Investigation of Leading Edge Contouring and External Cooling on a Transonic Turbine VaneDetta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : Efficiency improvement in turbomachines is an important aspect in reducing the use of fossil-based fuel and thereby reducing carbon dioxide emissions in order to achieve a sustainable future. Gas turbines are mainly fossil-based turbomachines powering aviation and land-based power plants. LÄS MER
2. Aerodynamic Investigations of a High Pressure Turbine Vane with Leading Edge Contouring at Endwall in a Transonic Annular Sector CascadeDetta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : Efficiency improvement is an important aspect to reduce the use of fossil-based fuel in order to achieve a sustainable future. Gas turbines are mainly fossil-fuel based turbomachines, and, therefore, efficiency improvement is still the subject of many on-going research activities in the gas turbine community. LÄS MER
3. Numerical and Experimental Investigations of Design Parameters Defining Gas Turbine Nozzle Guide Vane Endwall Heat TransferDetta är en avhandling från Stockholm : KTH
Sammanfattning : The primary requirements for a modern industrial gas turbine consist of a continuous trend of an increasing efficiency combined with very low emissions in a robust, cost-effective manner. To fulfil these tasks a high turbine inlet temperature together with advanced dry low NOX combustion chambers are employed. LÄS MER
- Detta är en avhandling från Stockholm : Energiteknik
Sammanfattning : This thesis deals with a study of the significance of lossmodels and their applications in simulation and optimisation ofaxial turbines. The design of a turbomachine system is a verycomplex engineering operation which can be looked upon as aniterative procedure made of various steps. LÄS MER
