Cracks that develop in concrete due to tensile stresses can lead to the corrosion of embedded reinforcing steel, which is a primary cause of concrete deterioration. It's common practice to introduce additional reinforcement to limit crack width in concrete. Another potential solution involves partially substituting concrete with alternative...

Many of the high-performance portable electronics and electric vehicles (EVs) on the market depend on lithium-ion batteries (LIBs) as their primary energy source. If millions of EVs are to be manufactured each year, rigorous resource management for EV battery manufacturing, as well as a material- and energy efficient 3R system (reduce, re-use,...

Passivating contacts in the front-rear contacted c-Si solar cells enhances the device performance by quenching the contact recombination and enabling sufficient carrier transport. Tunneling oxide passi- vating contact (TOPCon) which consists of an interfacial oxide and a poly-SiO𝑥 layer is one of the most promising contact techniques in...

Aerodynamic load determination through integration of the surface pressure distribution is limited in accuracy by the discrete number of measurements taken. Therefore, typically relatively large numbers of spatially distributed measurements are required which increase setup complexity, latency, cost and weight while requiring physical access in...

The state-of-the-art design approach of composite structures in Formula One (F1) rely on expensive full-scale crash tests and simple models that cannot describe the underlying physical phenomena during crushing. Although the models can describe the crush forces and resulting accelerations, their predictive capabilities are poor, and several...

After the breakup of the Stratos III vehicle, inertial roll coupling was pinpointed to be the root cause. In order to battle the problem a propulsive roll control system was suggested to keep the roll rate under acceptable bounds. A restartable hybrid rocket engine using nitrous oxide and ABS plastic was proposed. 27 tests have been performed of...

In this thesis a method of combined PIV and LIF experiments on the Turbulent/Non-Turbulent interface (TNTI) of a round jet is presented.<br/>By varying the distance from the nozzle in the measurements, the Kolmogorov scale of a large range of Reynolds number (2×10<sup>3</sup> ≤ Re ≤ 48×10<sup>3</sup>) is kept constant, allowing for a constant...

Lebbeus Woods was an experimental architect best known for his visionary drawings. His entry into the field of experimental architecture was enabled by the conditions in which the field found itself in the 1970s. Through drawing, Woods explored ideas and hypotheses which were unbound from conventional limitations. The field of architecture has...

When sailing in heavy seas, it happens that the water washes over the bow. This shipping of water is generally divided into two types. The term white water is used when the water is more of a spray and is generally harmless. Green water is more violent and can pose a danger to the crew and structures on board. <br/><br/>Research on green water...

The distribution of multiple materials within a single structure is a strategy that various biological systems rely on to achieve outstanding mechanical performances. These biological examples illustrate the effective utilization of hard rigid and soft flexible materials in particular. The proper composition of such hard-soft materials exceeds...

Mobile soft robots show great potential for exploration of unknown and hard to navigate environments. Sadly, most of these robots are currently being held back by their power sources and control systems. These components, which are usually quite heavy and bulky, need to be integrated before mobile soft robots can cut their tethers and explore...

This work presents an experimental and analytical investigation of unsteady loading of a low Reynolds number propeller and its relation to aeroacoustics. The propeller is positioned at an angle of attack with respect to the freestream which causes a variation in loading along the azimuth. The propeller is operated at 4000 RPM with an advance...

The control and design of kites for airborne wind energy requires an extensive understanding of kite dynamics. While these have been thoroughly analyzed with fluid-structure interaction models, very little experimental data exists to validate them. Specifically, most experiments on kites so far have not obtained local measurements that can be...

The reduction of turbulent skin-friction drag has the potential to generate numerous societal benefits. In large-scale industrial applications, the largest share of energy consumption goes into overcoming the friction drag produced by turbulent boundary layers formed on the outside wall. Estimates assess that over 50% of the total fuel burn is...

Breaking water waves still represent a very active research area, as they are involved in a broad spectrum of situations ranging from safety at sea to climate change. The detailed knowledge of the location of the free surface in case of breaking waves or wave impacts could prevent structural damages, increase the efficiency of ship hulls and...

Decarbonisation can be done through various routes: reducing the final energy consumption by improving process conditions and efficiency, reusing waste heat and by an outright energy transition to renewable sources. In this study, the focus is on reusing waste heat. Heat pumps have the potential to drastically reduce energy requirements in the...

Additive manufacturing (AM), or 3D printing, is emerging as a technology for different applications made of steel. It is expected that in the coming years the construction industry will benefit from the free and lightweight forms that can be fabricated and the possible material savings. A few experimental results of 3D printed stainless steel...

In a effort to curb climate change, more and more countries are adding solar and wind farms to their electrical grid. These solar and wind farms produce electrical energy based on environmental conditions, for example solar irradiation intensity or wind speed. As such these farms create fluctuations in the electrical grid and create a mismatch...

After more than 85 years, the iconic Afsluitdijk is in need of a reinforcement. During the latest safety assessment of Rijkswaterstaat the dike did not meet the standards at two components; the amount of wave overtopping (&gt;10 l/m/s) and armour stability. This research goes into detail about the overtopping on the Afsluitdijk. In the new...

This study presents the results of small scale flume experiments on a submerged rectangular cylinder subjected to a current, regular wave and combined wave-current environment. The objective of the study is to gain more knowledge about the hydrodynamics around and the kinematics of a submerged structure, to give a contribute to the research...
