1. Simulation in university chemistry education : cognitive and affective aspects
Abstract : This thesis undertakes two main tasks; to explore, within the authentic educational context, variables that influence the quality and outcomes of the knowledge-constructing activity during the simulation exercise; and to find appropriate instruments and methods to measure these variables, processes and outcomes. Closed-ended tasks that provided a high degree of structure, i. READ MORE

2. Numerical methods for load and response prediction for use in acoustic fatigue
Abstract : Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have three main limitations. First, they do not say anything about the load intensities. READ MORE

3. Exploiting the Synergies from Coupled Electricity and Heat Distribution Networks : Modelling, simulation and optimization based on an extended energy hub approach
Abstract : Recent literature shows that there is a significant potential of decarbonisation and efficiency improvement that can be achieved through the synergy from multi-energy systems (MESs). Coupling technologies, such as co-generation plants, heat pumps and thermal storages are widely recommended as means of unlocking additional flexibility and increasing the penetration of renewables in the heating and electricity sectors.

4. Experimental Study on Truck Related Power Losses: The Churning Losses in a Transmission Model and Active Flow Control at an A-pillar of Generic Truck Cabin Model
Abstract : The fight with global warming constantly forces vehicle manufacturers to innovate, in order to be able to reduce the CO2 emissions of their product. This means that marginal efficiency gains in every component are considered beneficial for total reduction of CO2 emissions. READ MORE

5. Transonic flow: large eddy simulation, numerical methods and subgrid modeling
Abstract : Shock wave turbulent boundary layer interactions (SWTBLI) commonly arise in turbomachinery and aerospace applications and on the exterior of high speed aircrafts. In all these cases, SWTBLI can significantly change the flow and hence the physical load imposed by it. READ MORE
