On March 24, 1969, the new wind-wave flumes at the Delft Hydraulics Laboratory (Figures 5 and 6) were officially opened by the Director-General of the Rijkswaterstaat. The design work started in 1964, and the building and installations 1tlere completed in November 1968. A general description of this equipment and some insight into its underlying...

While the shale revolution was largely a US’ affair, it affects the global energy system. In this paper, we look at the effects of this spectacular increase in natural gas, and oil, extraction capacity can have on the mix of primary energy sources, on energy prices, and through that on internal political stability of rentier states. We use...

Fluvial systems in which peat formation occurs are typified by autogenic processes such as river meandering, crevasse splaying and channel avulsion. Nevertheless, autogenic processes cannot satisfactorily explain the repetitive nature and lateral continuity of many coal seams (compacted peats). The fluvial lower Palaeocene Tullock Member of...

In deep sea mining polymetallic nodules are harvested that are found in large parts of the oceans at depths of up to 6000 metres. A deep sea mining system collects such nodules using a seabed crawler and transports them to a continuously sailing ship by pumping them via a jumper through a free-hanging riser. The position of the seabed crawler...

Rotating wickless and stationary capillary cylindrical heat pipes are widely used heat transfer devices. Transient behavior of such heat pipes has been investigated numerically with computational fluid dynamics and lumped parameter models. In this paper, the advantages of both methods are combined into a novel engineering model that is low in...

A new concept for energy efficient annealing of steel strip comprises of multiple rotating heat pipes. Each heat pipe extracts heat from the cooling strip which is reused to increase the temperature of the heating strip. In this context, the heat transfer between the steel strip and the rotating heat pipe is investigated. When the strip is...

The value of travel time can theoretically be defined as the opportunity cost of travel minus the direct utility from spending the time during the trip. This paper searches for empirical evidence to support this formulation. We show that travellers who indicate that a shorter trip duration is useful or a longer trip duration is very...

A large part of freight transport movements are part of a multimodal transport chain, in particular for port-related containerized transport flows. Because data of multimodal transports are unavailable it is challenging to develop a multimodal transport chain models. This paper describes the development of a new module for multimodal transport...

The effective fracture behavior of a fiber-reinforced composite depends on both the design and manufacturing of the material. During manufacturing several type of defects can occur. One of these defects are micro-voids on the sub-ply level. These can consist of either matrix voids or gaps between the fibers due to the inability of the resin to...

At the United Nations Climate Change Conference held in Paris in 2015, ambitious goals for the worldwide CO2 emissions were set. To achieve these goals, a huge reduction in CO2 emissions must be realized. For the energy market, the current aim is to use renewable electricity instead of fossil fuels. However, there are multiple sectors where...

A conventional dynamic positioning system is used to control vessel motions in the horizontal plane, i.e. surge, sway and yaw. However, the safety and operability of several offshore operations can be increased when also the roll motion is actively controlled, especially in beam seas. A control system model is proposed for combined thruster...

Waterborn transport currently runs on diesel driven Internal Combustion Engines<br/>(ICE). To reduce Green House Gas (GHG) emissions an option is to shift towards<br/>alternative fuels, like alcohols. This thesis focusses on methanol in ICEs. The<br/>combustion of methanol in ICEs can be done in numerous manners, where fuel<br/>altering,...

Hydrogen technology offers a promising opportunity to mitigate problems that arise due to the energy transition. It can enable storage and balancing for surplus in electricity production from intermittent resources as solar energy and wind power. Electrolysis converts green electricity into hydrogen. Hydrogen is suggested to be introduced into...

The breakage behaviour of biomass pellets with a diameter of 6 mm under uniaxial compression test was studied experimentally and numerically using the discrete element method (DEM). Two types of the available bonding contact models in EDEM software were used to compare the macroscopic properties including the maximum stress at failure, strain at...

Opportunities for academic libraries to enrich their products and services through facilitating open education (OE) in higher education are presented in an overview of good practices. A case study of open textbook publishing was performed at TU Delft to study how these products and services could stimulate educators to adopt OE. A simplified...

This thesis reports on the research and design of a real-time Time-Varying Model Predictive Control (TVMPC) scheme to stabilize a tilt-rotor aircraft with four independently tilting rotors. The aircraft design stems from a prototype system constructed by the drone technology start-up Avy.<br/>First, a motivation is presented for implementation...

The emergence of the Internet of Things (IoT) as the new paradigm of Information and Communication Technology (ICT) and rapid changes in technology and urban needs urge cities around the world towards formulating smart city policies. Nevertheless, policy makers, city planners, and practitioners appear to have quite different expectations from...

Time-of-day (TOD) choice can be considered as a fifth stage in the modelling of transport behaviour, additional to the conventional four stages. Twenty years ago in The Netherlands, a stated preference (SP) study was designed for investigating the choice of time-of-day (departure time) and transport mode. A nested logit time period and mode...
