Teixidó, Helena (author), Caglar, Baris (author), Michaud, Véronique (author)Visualization of resin flow progression through fibrous preforms is often sought to elucidate flow patterns and validate models for filling prediction for liquid composite molding processes. Here, conventional X-ray radiography is compared to X-ray phase contrast technique to image in-situ constant flow rate impregnation of a non-translucent...conference paper 2022

Van Rheenen, E.S. (author), Padding, J.T. (author), Slootweg, J.C. (author), Visser, K. (author)Increasing pressure on the reduction or elimination of the use of fossil fuels in shipping requires the application of new maritime fuel alternatives. Green and circular produced hydrogen as a maritime fuel in fuel cell systems offers a great solution for these concerns. A fuel cell system has a zero emission performance, solid state silent...conference paper 2022

Yang, Zhengxian (author), Shi, Peng (author), Zhang, Yong (author), Li, Z. (author)The influences of liquid-binder ratio and mixing sequence on the performance of superabsorbent polymer (SAP)-containing alkali-activated slag (AAS) mortar are investigated in this study. It is found that the SAP absorbs much less liquid in upper supernatant of AAS than in water. Mixing SAP with liquid first induces a larger absorption...journal article 2022

Estrella, Jorge (author), Wüthrich, D. (author), Chanson, Hubert (author)A hydraulic jump is a region of rapidly-varied flow that is extremely turbulent. While the one-dimensional continuity and momentum principles have been successfully applied to express the relationships between upstream and downstream conditions, the three-dimensional equations cannot be resolved without some complicated turbulence closure,...journal article 2022

Martinez Garcia, M. (author), Sattar, M.A. (author), Atmani, Hanane (author), Legendre, Dominique (author), Babout, Laurent (author), Schleicher, Eckhard (author), Hampel, Uwe (author), Portela, L. (author)The performance of multiphase flow processes is often determined by the distribution of phases inside the equipment. However, controllers in the field are typically implemented based on flow variables, which are simpler to measure, but indirectly connected to performance (e.g., pressure). Tomography has been used in the study of the...journal article 2022

(author), Cui, Hao (author), Li, Yulong (author)Rain erosion may cause substantial damage to aircrafts during supersonic flight. Such event is investigated here via high-speed waterjet impact on composite laminates. An experimental setup is developed to produce waterjets with the speed up to 700m/s and a finite element model of the waterjet-composite impact event is established. The...journal article 2022

(author), Verweij, M.D. (author)Common clamp-on ultrasonic flow meters consist of two single-element transducers placed on the pipe wall. Flow speed is measured noninvasively, i.e., without interrupting the flow and without perforating the pipe wall, which also minimizes safety risks and avoids pressure drops inside the pipe. However, before metering, the transducers have...journal article 2022

Chavez Tapia, M.A. (author), Xu, M. (author), Wu, Zehang (author), Zuniga, Marco (author)A recent development in wireless communication is the use of optical shutters and smartphone cameras to create optical links solely from ambient light. At the transmitter, a liquid crystal display (LCD) modulates ambient light by changing its level of transparency. At the receiver, a smartphone camera decodes the optical pattern. This LCD-To...journal article 2022
