In the realm of fluid dynamics and particle transport, the control of particle trajectories represents a formidable challenge. It would be useful to be able to optimally navigate an oceanographic float from one pre-set location to another by solely changing its buoyancy. In this thesis, a first step in discovering whether this is possible and...

Geothermal energy can be promising to help the energy transition. Warm water is pumped up from a geothermal well and after it is cooled down, the cold water is reinjected into the hot aquifer underground. The temperature change could cause chemical balances to be disturbed and result in precipitation on the porous medium of the aquifer. This...

In dit verslag is een eolisch sedimenttransport model geformuleerd en het model van De Vries geïmplementeerd en geanalyseerd. Na de afleiding van de eendimensionale advectie-diffusievergelijking vanuit de driedimensionale continuïteitsvergelijking is eerst het model van De Vries zonder diffusie onderzocht. In het model kan er onderscheid gemaakt...

In several experiments, enzymes have shown an in increase in diffusivity in the presence of their substrate. The enhancement in diffusivity ranged from as low as 28% for urease to 80% in the case of alkaline phosphatase. There are two main competing theories. One asserts that catalytically driven boosts propel the enzyme forward in ‘leaps’,...

Due to climate change, the sea temperature is rising. This temperature change has an effect on the phytoplankton population. Phytoplankton is responsible for more than 50 percent of the oxygen production on earth, and is therefore crucial for life on earth. In this report, the research question is: is the temperature increase of the water...

Welding is an extensively used technology by different industries such as aerospace, automotive and marine industry. Welding involves the temporal melting of materials in order to join them together. The quality of the weld is known to depend on the fluid flow and heat transfer in the material. A way to influence the heat transfer and fluid flow...

Vapour Distribution Boxes (VDBs) are used for continuous Physical Vapour Deposition (PVD) coating. The present study shows a Computational Fluid Dynamics (CFD) simulation of Zinc vapour inside a VDB, analyses the lateral Zinc vapour distribution and identifies regions in which phase change is likely to happen.

The aim of this study is to evaluate the performance of two methods for determining the speed of a ship relative to the water during a so called speed trial.<br/>The first method is called the Mean of means method and has been traditionally. The second is called the Iterative method and has been recently developed and is already used for speed...

This project can be divided into two parts. The goal of the first part is to numerically implement the Cahn-Hilliard equation in one dimension both explicitly and implicitly. This will be done using Matlab. The goal of the second part is to validate the coupled Cahn-Hilliard-Navier-Stokes equation and the dynamic boundary condition for moving...

The lifetime of a gas well is significantly influenced by the liquids present in the well. These liquids can be found along the walls in an annular flow and is carried up along with the gas as a result of the relatively high gas pressure in the early stages of the well. As time goes on the gas pressure decreases, thus the well’s ability to drag...

Magnetic Drug Targeting is a relatively new technique whereby chemotherapeutic agents are attached to magnetic particles that will be injected in an artery upstream of an affected area. By exerting an external magnetic field an internal magnetic field gradient will be induced that will entrap the particles that contain the drugs in the affected...

The goal of this project is to validate and evaluate developed numerical solvers that solve both the Cahn-Hilliard diffusion equation and the Cahn-Hilliard-Navier-Stokes coupled equations. The solvers are written for the implementation in the open source CFD software platform, OpenFOAM.

Worldwide, welding is a multi billion-dollar fabrication technology used extensively in construction and industry. The final quality of a weld is known to be dependent on the hydrodynamics in the liquid region and the energy transfer in the surrounding heat affected zone. Understanding of these processes is therefore vital in improving weld...

Patient specific drug delivery may improve the efficiency of the medicine and reduce the side-effects. In addition to different medicines and dosages, the target site of the medicine can differ from patient to patient. By using drug particles with a magnetic core, and under the influence of a magnetic field, the particles may be steered towards...

For this study, Urban Heat Island (UHI) consequential urban atmospheric thermally stratified buoyancy influences were investigated, utilising an in-house Computational Fluid Dynamic (CFD) modelling code, SARA3DCLIMAT. The code is based on transient-Reynolds Averaged Navier-Stokes (T-RANS) and hybrid Large Eddy Simulation (LES)/T-RANS methods,...

This research aims to accurately predict the flow of electromagnetically conducting liquids liquid steel in a thin cavity. A thin cavity, with a thickness « width, is relevant as a model for a continuous steel caster mould. A turbulent jet flow enters the cavity, leading to a quasi-two-dimensional flow. Using large eddy simulations with the...

In many processes, for example trickle-bed reactors, it is important to completely wet small spheres, or particles. (Baussaron, et al., 2007) Ideally, a small stream of liquid on such a particle would create a film around the particle, completely wetting it. It is therefore interesting to investigate which factors influence the formation of this...
