A New Data Treatment for the Construction of Surrogate Models from Partially Sampled Design Spaces

As technology advances, industry and academia rely more and more on the output of computer simulations or physical experiments of engineering systems under development. In some cases, the relationship between input and output of a system under study is too complex to model through analytical expressions or numerical methods. In other cases,...

Reduced-order modelling for prediction of aircraft flight dynamics: Based on indicial step response functions investigating agile aircraft undergoing rapid manoeuvres

During aircraft design,multiple tools are utilised to inspect the performance of the configuration. As the design matures, higher fidelity analyses are conducted to predict the flight dynamics of the aircraft. These analyses are conducted by using semi-empirical relations, numerically analysing flow behaviour, conducting wind-tunnel tests and...

Chemical Reactor Network for LDI Combustor: CRN development and Analysis of Different Fuels

Prediction of emissions from combustion systems is a complex problem involving the coupling between the flow field and chemistry. CFD analysis is the most commonly employed approach. However, it has the drawback that a very high computational cost prevents the use of detailed chemistry models. This master thesis, which focuses on NOx emissions,...
