We spent hours sitting in silence, until he turned his eyes away from the window and spoke: ‘I would like to tell you one last story, It has been decided, there will be no more travels beyond the edge for me.’ In the following days I heard, not one but five, stories of people M encountered – inhabitants of the land he traveled to. Truth be told,...

This work introduces the Surrogate Advisory System (SAS), a Python package that aims to reduce the existing complexity when working with surrogate-based MDAO systems. SAS automates most of the steps for a CPACS-based MDAO workflow and drastically reduces required efforts to integrate surrogate models within MDAO systems. Key developments...

In offshore operations a trend is forming where vessels are more often required to do multiple short operations within a small-time frame. Traditional mooring systems require execution time far beyond the operation time. Dynamic positioning systems offer great advantages for short time span operations such as crew transfer or lift operations. ...

The Flying V is an innovative new aircraft concept currently being developed by the faculty of Aerospace Engineering at Delft University of Technology. This aircraft is a flying wing having a large sweep on the inner section, and a small sweep angle at the outer, giving the aircraft its characteristic V shape. The objective of this research is...

The International Maritime Organisation (IMO) is a specialized agency responsible for the safety and security of shipping and the prevention of marine and atmospheric pollution by ships. Air pollution is one of the contributors, CO2 emission is recognised as the biggest contributor to the increasing temperature of the Earth. Global warming is a...

Besides wastewater and rainwater, the sewers in the Netherlands also transport a lot of water that is not supposed to be in the sewer. This water is called extraneous water and is the result of unwanted discharges in the sewer system. This could be groundwater infiltrating leaky sewer pipes, or pumped from construction sites directly into the...

This thesis investigates the potential of a large pumping station in IJmuiden, the Nether-lands, for participating in Demand Response. Due to climate change, renewable energy is onthe rise. The intermittency of energy, together with its unpredictable supply, are a big hurdlefor the energy transition. Two methods are promising solutions to this...

Heatpipes are promising devices for geothermal energy extraction owing to their<br/>effectiveness to transport heat. The goal of this research is to validate an analytical heatpipe model with experiments and to investigate the difficulties in designing and constructing geothermal heatpipes. There is a lack of literature and research concerning...

The main objective of this study was to develop a quick model for an oil free twin screw compressor. The computational time of the model was to be kept as low as possible so that the model could be used for quick estimations and optimizations of the process. This was done by using a simple geometry focusing on the volume curve and port sizes,...

This thesis is a study on the cracking behaviour of road bases constructed with cement bound reclaimed asphalt (also known in the Netherlands as AGRAC). It is decided to focus on this material because of the few researches available on the topic although the material being widely applied, at least in the Netherlands. The<br/>goal of adding...

Despite the fact that the price per watt-peak for photovoltaic modules are decreasing rapidly, there is a large population of people which have still not implemented photovoltaic technology in their everyday lives. An important reason why PV is still not the main source of electrical energy for these people is the uncertainty that comes with...

In this thesis diffuser performance will be simulated with computational fluid dynamics, which will be done with the program Ansys Fluent. The expanding geometry creates an adverse pressure gradient and under certain conditions there will also be separation.<br/><br/>At first a relative simple simulation will be done of a one-directional...

The influence of using different chemistry model and different chemical kinetics schemes on modeling combustion inside a rocket engine igniter are investigated. An igniter for a LOX/CH4 rocket engine is designed and a CFD model is developed which is used to model the designed igniter. Verification and validation methods are discussed.<br/><br/>...

Many regions in the world depend heavily on expensive desalinated water for fresh water consumption, in particular tropical areas. Current mainstream desalination technologies (Reverse Osmosis and Multi-Stage Flash Evaporation) are quite energy intensive and thus costly. Today’s challenge is to design a desalination system that could run with...

For conceptual aircraft design to include accurate laminar flow prediction, a link between modern computational tools to determine laminar-to-turbulent boundary layer transition and fast sizing methods is required. For swept wings, it is crucial to include the highly unstable three-dimensional crossflow component of the boundary layer. These...

Biomass as a renewable energy resource and a carbon neutral feedstock has a big potential to replace fossil fuel. Gasification as one of thermochemical process routes in biomass utilization draws attention with regards to its broad product range. The circulating fluidized bed with the advantages of higher and rapid conversion performs as the...

Wind turbines are often grouped together for financial reasons, but due to wake development this usually results in decreased turbine lifetimes and power capture, and thereby an increased levelized cost of energy (LCOE). Wind farm control aims to minimize this cost by operating turbines at their optimal control settings. Most state-of-the-art...

There are still important knowledge gaps regarding stability and safety of bicycle riding. Every year around 60,000 people need hospital treatment for single sided accidents in the Netherlands alone. Supporting the need for understanding lateral bicycle dynamics. One of the prominent disturbances on lateral bicycle and rider behaviour is...

Models are an important tool for decision making. However, in order to get proper results, these models must be validated and only be used in situations where the conditions of the validation apply. Blind trust on a model can lead to unexpected and inaccurate results. Advancements can be made to reduce the number of situations where this occurs....
