1. Experimental Studies of Effusion Cooling
Abstract : The desire to increase the efficiency of jet engines, has led to an increase in the temperature in the combustion chambers and in the turbine stage. There is thus an interest in efficient cooling methods. Film cooling and effusion cooling are often used where there is a great heat load. READ MORE

2. Aerodynamic Investigation of Leading Edge Contouring and External Cooling on a Transonic Turbine Vane
Abstract : 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. READ MORE

4. Processability of Laser Powder Bed Fusion of Alloy 247LC : Influence of process parameters on microstructure and defects
Abstract : This thesis is about laser powder bed fusion (L-PBF) of the nickel-based superalloy: Alloy 247LC. Alloy 247LC is used mainly in gas turbine blades and processing the blades with L-PBF confers performance advantage over the blades manufactured with conventional methods. READ MORE
