Combustion is and remains for the foreseeable future an essential chemical process. The physical and mathematical modelling of such processes can help to optimise the design and operation of combustion furnaces which is critical for fuel efficiency. Given the combined complexity and interaction of the gas flow dynamics and the reaction processes...

In this Bachelor project we researched the applicability of finite difference methods to solve the multi dimensional Westervelt equation. The Westervelt is an equation describing the propagation of a non-linear wave. The goal of this project was to solve the full Westervelt equation in higher dimensions. We used Julia for our implementations of...

In agricultural studies it is often important to predict the performance of genetically different plants. To make sure predictions are done well, it is necessary to make sure they are not influenced by effects of the field on which they are planted. These field effects or spatial effects are in practice often quite complicated and can be due to...

The energy transition will significantly impact distribution transformers as they will have to deal with more load on them, which is also more variable due to renewable energy sources. However, currently, these transformers are often not monitored with sensors. Therefore, the Dutch network operator Stedin asked to investigate the possibilities...

In the present era of environment-friendly and clean combustion systems, there is an increasing demand for fast and accurate tools for emission predictions. The best choice is the CFD-CRN method which is a combination of computational fluid dynamics (CFD) and chemical reactor network (CRN) for decoupled simulation of fluid flow and detailed...

This essay shows a two dimensional implementation of the finite element method for the Westervelt equation. To do this the finite element method is first applied to the linear wave equation, then to non-linear diffusion and finally to the Westervelt equation. Both an element by element and a faster vectorized implementation are given for the...

Heat transfer by radiation is something you experience everyday: when walking outside in the sun or when cooking your diner. This thesis provides understandable models of the role that radiation plays in the transfer of heat. By studying literature we developed a mathematical basis for the heat transfer model, where we discuss diffusive,...

This thesis covers the power load flow problem and three numerical methods which can be used as a solution. We firstly discuss the concepts from electrical engineering required to discribe the problem. This includes alternating current and voltage and admittances of various electrical elements. We then use these concepts to derive a set of...

A high-resolution hydrological solver that solves on time-adaptive grids is created. The solver uses h-refinement strategies which adapts the resolution of the grid using a posteriori measure. It is based on an open-source scientific computing library named PETSc. With the use of highly scalable time-stepping solvers provided by PETSc, an...

Decreasing NOx emissions is becoming increasingly important as it has many lifechanging implications on humanity and nature. In this work several models were constructed to simulate the combustion of methane in a cement rotary kiln, and it was investigated whether oxygen-enhanced combustion leads to less NO<sub>x</sub> production for the...

In this work, the parareal algorithm is analysed and executed on the model for combustion of methane. The parareal algorithm is designed to generate an approximation to an initial value problem faster than a serial numerical time-integration method by using two propagators, the coarse propagator and the fine propagator. With the use of two...

Anode baking is a huge part of the Aluminum industry. The quality and characteristics of the anode blocks will be formed in the anode baking furnaces. The process itself is very expensive, time consuming and ecologically unfriendly. From the other hand, anode baking process can use its own waste as a secondary fuel source. Here, by waste we mean...

The calculation of power flow through electrical networks has been utilized commonly in transmission networks as the first calculation tool to assess their steady state conditions. However, the current introduction of renewable micro-sources (many of them single-phase connected) and the implementation of microgrids makes the calculation of power...

Astrophysical photons with a sub-millimetre wavelength are of great value to research star and galaxy formation. Superconductors have a small energy gap with which these sub-millimetre photons can be measured. Superconductors can absorb photons so that quasiparticles are created, which will in turn change the complex conductivity: incoming...
