1. Characterization of train-induced aerodynamic loads on high-speed railway vertical noise barriers
Sammanfattning : High-Speed Railway (HSR) technology requires the deployment of noise barriers to mitigate noise pollution affecting nearby residents. As train speeds increase, so does the magnitude of aerodynamic effects such as aerodynamic noise and the pressure on these barriers, meaning that these structures require robust sound insulation and structural load-bearing capacities.

2. Multimethod aerodynamic research of engine-realistic turbine rear structures
Sammanfattning : Despite the significant advancements in aircraft engine technology over the past years, the aerodynamics of engine-realistic turbine rear structures (TRS) remain largely unexplored. The TRS, a structural and aerodynamic component situated downstream of the low-pressure turbine (LPT), plays a pivotal role in engine aerodynamic performance, deswirling the LPT flow to maximize the engine thrust.

3. Conceptual Thermodynamic Cycle and Aerodynamic Gas Turbine Design - on an Oxy-fuel Combined Cycle
Sammanfattning : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.

4. Aerodynamic measurements of normal voice
Sammanfattning : Vocal fold vibration results from an alternating balance between subglottal air pressure that drives the vocal folds apart and muscular, elastic, and restoring forces that draw them together. The aim of the present thesis is to present quantitative data of normal vocal function using a noninvasive method. LÄS MER
5. Aerodynamic design framework for low-pressure compression systems
Sammanfattning : Aircraft engine manufacturers strive to improve current state of the art designs through continuous development efforts. By improving existing designs and exploring new alternatives, the goal is to reduce the fuel consumption - a topic of high relevance due to the remarkable growth rate of air traffc. LÄS MER
