Smith, Caitlin (author), Shepherd, Jami (author), Renaud, G.G.J. (author), van Wijk, Kasper (author)We present a technique called photoacoustic vector-flow (PAVF) to quantify the speed and direction of flowing optical absorbers at each pixel from acoustic-resolution PA images. By varying the receiving angle at each pixel in post-processing, we obtain multiple estimates of the phase difference between consecutive frames. These are used to...journal article 2024

(author), Westerweel, J. (author), Suijker, W. (author), van Wijk, R. (author)The principal aim of the work presented here is to investigate and demonstrate that a forward tilted rowing blade would result in a more efficient and effective motion of the blade through the water that would result in a higher boat speed when an equal input power is provided. A 1:5 scaled rowing boat is used to determine the performance of...journal article 2023

van der Roest, E. (author), Bol, Ron (author), Fens, T.W. (author), van Wijk, A.J.M. (author)Recovery of heat from electrolysers is potentially interesting to increase the total system efficiency, reduce CO<sub>2</sub> emissions, and increase the economic feasibility of both hydrogen and heat production. This study examines different designs for the utilisation of (waste) heat from a 2.5 MW<sub>el</sub> polymer electrolyte membrane ...journal article 2023

de Hoog, E. (author), van Wijk, J. M. (author), Talmon, A.M. (author), van Rhee, C. (author)Density wave amplification in hydraulic transport pipelines forms a high risk to operational continuity, as density waves can lead to system blockages or centrifugal pump drive failures. Recent experimental research, in pipelines which contain long vertical sections, has shown that density waves can amplify at velocities far exceeding the...journal article 2022

van Wijk, Robert (author), Lazcano, Andrea Michelle Rios (author), Akutain, Xabier Carrera (author), Shyrokau, B. (author)Modern Advanced Driver Assistance Systems (ADAS) are limited in their ability to consider the driver's intention, resulting in unnatural guidance and low customer acceptance. In this research, we focus on a novel data-driven approach to predict driver steering torque. In particular, driver behavior is modeled by learning the parameters of a...journal article 2022

van Wijk, J. M. (author), de Hoog, E. (author), Talmon, A.M. (author), van Rhee, C. (author)The hydraulic transport of sediments in sediment–water multiphase mixtures is an important process in nature and many industrial applications. The flows are characterized by complex transient phenomena, in which the overall system scale and the particle scale are equally important. Experimental research into dense mixture flows is focused on...journal article 2022

Hellinga, C. (author), van Wijk, A.J.M. (author)De belangstelling voor waterstof als energiedrager voor de gebouwde omgeving<br/>ontwikkelt zich snel. Veel indicatoren wijzen inmiddels in de richting dat waterstof een significante bijdrage gaat leveren in de verduurzamingsopgave, ook voor ruimteverwarming. Essentieel is de beschikbaarheid van een grootschalige infrastructuur voor...book chapter 2021

Chrysochoidis-Antsos, N. (author), van Bussel, G.J.W. (author), Bozelie, Jan (author), Mertens, Sander M. (author), van Wijk, A.J.M. (author)Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical cosθ theories for yaw misalignment did not...journal article 2021

Ghotge, R. (author), van Wijk, A.J.M. (author), Lukszo, Z. (author)This work analyses the effectiveness of an off-grid solar photovoltaic system for the charging of electric vehicles (EVs) in a long-term parking lot. The effectiveness of charging is investigated through analysis of the states of charge (SoC) at departure of EVs plugged in at the parking lot over the simulated year. Although the share of...journal article 2021

Froeling, H. A.J. (author), Dröge, M. (author), Nane, G.F. (author), van Wijk, A.J.M. (author)With the advent of large-scale application of hydrogen, transportation becomes crucial. Reusing the existing natural gas transmission system could serve as catalyst for the future hydrogen economy. However, a risk analysis of hydrogen transmission in existing pipelines is essential for the deployment of the new energy carrier. This paper...journal article 2021

Wang, L. (author), Qin, Z. (author), Slangen, T (author), Bauer, P. (author), van Wijk, T (author)With growing concern on climate change, widespread adoption of electric vehicles (EVs) is important. One of the main barriers to EV acceptance is range anxiety, which can be alleviated by fast charging (FC). The main technology constraints for enabling FC consist of high-charging-rate batteries, high-power-charging infrastructure, and grid...journal article 2021
