Simulation models are increasingly used to substantiate long-term planning policy decisions. The communication of model results from modellers to policy-makers has not received much attention by scholars. While, without correct interpretation and correct use of model results the quality of the model itself is irrelevant for the impact of the...

Heat exchangers of any kind are exposed to thermal loading which have the potential to cause severe stresses on the equipment. The magnitude of these loads are far more pronounced when temperature differences occur. These may be during plant start-up or shut-down due to the transient nature of the temperature profiles or even imbalances that...

Recent innovations in the off-shore wind industry have lead to bigger wind turbines and taller support structures. These towers can suffer from vortex-induced vibrations (VIV). The present work couples the open-source CFD solver OpenFOAM with a structural solver to investigate these fluid-structure interactions (FSI) effects in more detail. 2D...

Micro-Doppler patterns of multi-propeller drones measured by radar systems are widely used in the classification of different drones, since the micro-Doppler patterns illustrate the velocity and motion properties of the drones. However, on this topic, there are a few issues the current researches have not tackled yet, and these will be discussed...

Variable steering systems have the ability to change the ratio between the steering wheel and the front wheels while driving. These adjustable steering systems have led to an improvement in traffic and road safety and decrease in driver’s workload. A previous study concludes that driver steering behaviour is significantly dependent on vehicle...

This research addresses a problem at Cargill Multiseed, where a gap exists between the desired performance of the production of sunflower oil and the current. This research is performed to improve the stability of the production process by removing the disturbances. After identifying the restrictions on the input and output of the production...

Due to connectivity problems, the attractiveness of public transport is limited. Policymakers aim to increase the modal share of public transport to protect the accessibility, livability, safety, sustainability and efficiency in the cities of the future. Applying Autonomous Mobility on-Demand (AMoD) systems as a feeder service for public...

Block signalling and Automatic Train Protection are two of the main railway safety systems to control the risk of train accidents. The combination of the existing Dutch block signalling system NS’54 and ATP-system ATB-EG is functioning well, but has some drawbacks. The systems have been designed over 60 years ago with proven technology of that...

Wind machines are used to prevent or mitigate the adverse effects of night frost in spring. These frost events occur during clear-sky, low-wind nights in which a thermal inversion builds up from the surface. The machines work by mixing and transporting warm air from aloft downward which consequently erodes the thermal inversion. Various studies...

Meteors have been observed by accident from geostationary orbit (GEO). It is of interest for surveillance, meteor science and the updating of empirical models to know what instruments are needed on a GEO satellite to observe meteors and re-entering capsules in Earth ‘s atmosphere. A re-entry simulation code is written to fill the gap of missing...

With an increase in amount of container terminals competition between terminals has risen. Therefore it has become more and more important for terminal operators to conduct their work as efficient as possible. Efficient terminal operations are hindered by stochasticity, which is defined as random variation in parameter values. Due to missing...

This thesis is part of a greater effort to use machine learning for the development of flexible and universal unresolved-scale models in large eddy simulation (LES). The novelty in the current work is that a neural network learns to predict the integral forms of the unresolved-scale terms directly without a priori assumptions on the underlying...

In the European Union Road freight transport volume is expected to grow 78% between 2000 and 2030, which results in more trucks on the road network. The worldwide estimated trend shows an increase of 150 million freight vehicles and an increase of 240 million passenger vehicles. The growth of both vehicle classes will have a major impact on the...

Sedimentation of particle suspensions is a relevant process to a variety of applications, such as the reclamation of land and chemical engineering systems. Direct numerical simulations of the settling of a single, two and multiple solid spheres under gravity in a square duct have been performed. The simulations involve 4 different Galileo...

The canals of Amsterdam represent a draw for tourists and add to the value of real estate along the canals. More than 40 percent of Amsterdam tourists take a trip through the canals, accounting for more than 3 million canal travelers annually. Therefore, the tour boat sector is crucial for tourism in Amsterdam.
Many of the quay walls on...
