21. An anatomy of technological innovation in infrastructure and defence systems in Sweden after the Cold War
Sammanfattning : The dual interaction of science and technology with defence, security and infrastructures for service provision as energy is a major theme in modern times. The era after the Second World War and in the course of the Cold War was accompanied and spurred by an amazing number of great technological advances and changes. LÄS MER
22. Preliminary Design Investigations for the Selection of Optimum Reaction Degree for 1st Stage of a High Pressure Gas Turbine
Sammanfattning : One-dimensional (1D) turbine design calculation phase requires a handful of input data and choice of design parameters to provide the blade flow path geometry along with the flow kinematics and thermodynamics properties at the blade mid-span. The choice of important aerodynamics design parameters namely reaction degree, nozzle guide vane NGV exit flow angle or flow coefficient and stage loading defines the mid-span flow velocity triangles.

23. Investigation of thermal biomass gasification for sustainable small scale rural electricity generation in Uganda
Sammanfattning : With the increasing need for renewable energy technologies in the world, biomass fuel transformation technology is growing towards meeting that need, among others. Challenges remain certain and new innovations are being tested in bid to overcome them with the application of biomass as energy source. LÄS MER
24. Functional nanocomposites for advanced fuel cell technology and polygeneration
Sammanfattning : In recent decades, the use of fossil fuels has increased exponentially with a corresponding sharp increase in the pollution of the environment. The need for clean and sustainable technologies for the generation of power with reduced or zero environment impact has become critical. LÄS MER
25. Numerical and Experimental Investigations of Design Parameters Defining Gas Turbine Nozzle Guide Vane Endwall Heat Transfer
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
