Singh, Ankit (author)
Amidst the rise in fossil fuel consumption and the global energy crisis, there is a growing demand for clean, environmentally friendly, and sustainable energy solutions in industrial processes. One promising approach is to substitute conventional working fluids in power cycles with supercritical fluids. Over recent decades, substantial research...

PWN is responsible for supplying sufficient quantities of high-quality water to its customers. The growing population and the effects of climate change, such as heat waves and droughts, are straining the capacity of the water supply network, especially during dry and warm periods when water demand increases. A significant portion of the drinking...

Thermal convection is a phenomenon seen in almost all facets of life, ranging from planetary convection to ocean currents and convection inside the Earth. The physics of thermal convection complicates when a porous wall layer is present. Flow over urban canopies, forest canopies or flow in underground aquifers are classic examples where thermal...

Over the past few decades, there has been a significant increase in global energy consumption. To address the risks associated with climate change, there is an increasing urgency to transition towards renewable energy sources. With this growing demand, the interest in offshore wind energy has increased significantly, leading to the construction...

This investigation focuses on the premixed conical flame, a mainstay of combustion diagnostics. While extensive studies have explored high-frequency oscillations in the canonical Bunsen flame, little attention has been given to low-frequency oscillations affecting flame fronts. This thesis aims to explain the origins of these oscillations and...

The ramifications of plastic pollution on the environment are becoming increasingly serious in various forms throughout the world. In this context, rivers are the most important suppliers of plastics entering the marine environment. However, rivers that contain high loads of plastic waste also directly harm the livelihoods of people living near...

Due to global warming and the subsequent rise of the sea level, scarcity of land to build on, the continues increase of the world’s population and a shift in population from rural areas to the city, there is a need for innovative projects to tackle or deal with the increase of needed liveable area. One of the solutions is floating cities. A...

One of the biggest threats that humanity is currently facing is the climate change. The amount of greenhouse gases emissions and specifically the amount of CO2 in the atmosphere has increased and is projected to increase even more in the next years. One possible solution is the use of supercritical CO2 as an alternative working fluid in power...

To meet the targets set at the Paris climate convention, a rapid decrease in the emissions caused by the process of extraction of fossil fuels is required. Especially offshore, where a grid-connection is often non-existent, having power supplied by local renewable energy sources with a variable power generation can potentially lead to problems...

Research towards aquathermal energy solutions is still in a pioneering phase. Especially in urban environments, these solutions could potentially form the missing connection between heating supply and demand. This study focuses on the application of these solutions in the city canal waters in the largest city of the Netherlands, Amsterdam ....

Offshore pipelines represent major items in the oil and gas industry nowadays. These submarine pipelines are usually covered with backfill for protection and a well-known method for this is sand backfilling with a trailing suction hopper dredger (TSHD). Although pipeline installation with a TSHD is a developed technique, there are still some...

In current study, several fundamental and inherent problems in original Deardorff subgrid model are identified under stably stratified condition. It is found that the mixing length parameterization in this subgrid model is at the root of a long trouble problem of grid size sensitivity in large-eddy simulation (LES). A new formulation of mixing...

The thermal recovery efficiency of High Temperature Aquifer Thermal Energy Storage (HT-ATES) systems can be limited due to the effect of buoyancy flow of the injected hot water. This thesis has researched the application of a Multiple Partially Penetrating Wells (MPPWs) as a well design method to counteract the effect of buoyancy flow and...

This thesis focuses on the development of a computational model for early-stage design decision support of naturally ventilated terminal structures. The model is developed in a parametric Rhino Grasshopper environment paired with Python coding and CFD analyses through OpenFOAM. Optimization of air distribution parameters is performed with...

Schothorst, Quinten (author)
In this thesis a model is set up to assess the economic viability of early stage buoyancy design concepts. The main research question is to find out if a versatile design approach to the buoyancy lifting concept, i.e. being able to take on multiple projects, can result in an economical viable solution for decommissioning offshore platform...

For the E39 highway in Norway a project is underway to replace the ferry crossing in the Sognefjord with a fixed crossing. Previous thesis projects have resulted in a design for a 4500 m long buoyancy bridge which consists of 22 concrete pontoons that carry a steel truss superstructure. To reduce lateral movements the pontoons are fixed to a...

Yip, T. (author)
The purpose of this MSc thesis is to find a feasible concept for a circa 4500 m long buoyancy bridge, which is located at the Sognefjord in Norway. The concept should be structurally and aesthetically competitive. In contrast to bridges on shore with fixed supports, a buoyancy bridge is supported on floating pontoons. As result, loads will cause...

In the Netherlands, when a bored tunnel has to be constructed, a launch and a reception shaft have to be excavated to guarantee sufficient cover. This is necessary to ensure face stability, prevent uplift and risk of blow out. Moreover, especially in the western part of the Netherlands, the first 10 to 20 meters of soil consists of the Holocene...
