de Raad, B.W. (author), van Lieshout, Marit (author), Stougie, L. (author), Ramirez, Andrea (author)Steam generating heat pumps show great potential for reducing carbon emissions in the industrial sector. However, predicting their performance is challenging as the exergy destruction of e.g., compressors and expansion valves increases with the temperature lift and condenser temperature. With over seventy design improvements mentioned in the...conference paper 2023

Wang, N. (author), Verzijlbergh, R.A. (author), Heijnen, P.W. (author), Herder, P.M. (author)This paper reviews the literature on the modeling approaches on decentralized energy investment and operation in the prosumer era. The study has several contributions. Firstly, it adds investment models into the review which have not been previously reviewed for decentralized energy modeling. Secondly, a modeling framework consisting of four...conference paper 2020

Pimpalgaonkar, H.G. (author), van Steijn, V. (author), Kreutzer, M.T. (author), Kleijn, C.R. (author)We present a finite volume implementation of a phase field method in OpenFOAM as a tool to simulate reactive multiphase flows on heterogeneous surfaces. Using this tool, we simulate the formation and growth of a droplet due to a chemical reaction on a hydrophilic catalytic patch surrounded by a hydrophobic wall. We compare the growth dynamics...conference paper 2016

Pfeiffer, T.V. (author), Ortiz Gonzalez, J. (author), Santbergen, R. (author), Tan, H. (author), Schmidt-Ott, A. (author), Zeman, M. (author), Smets, A.H.M. (author)A soft deposition method for incorporating surface plasmon resonant metal nanoparticles within photovoltaic devices was studied. This self-assembly method provides excellent control over both nanoparticle size and surface coverage. Films of spherical Ag nanoparticles with diameter of ?100 nm were fabricated by depositing size-selected aerosols...conference paper 2014

(author)The main aim of this paper was to analyze possible utilization of the low concentration nanofluids and the magnetic field to enhance heat transfer. The studied fluids were based on water with an addition of copper particles (40-60 nm diameter). They belonged to the diamagnetic group of materials. As a first attempt to stated target the analysis...conference paper 2014

De Martin, L. (author), Bouwman, W.G. (author), Van Ommen, J.R. (author)recent years, the interest in fluidization as a mean to process nanoparticles is strongly increasing. Due to the small size of the nanoparticles, which makes van der Waals forces predominate, they do not fluidize as single particles but as agglomerates. Various researchers using settling experiments and bed expansion measurements conclude that...conference paper 2013

Latsuzbaia, R. (author), Negro, E. (author), Koper, G.J.M. (author)Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first...conference paper 2013

Koper, G.J.M. (author), Boekhoven, J. (author), Hendriksen, W.E. (author), Eelkema, R. (author), Van Esch, J.H. (author)Self-assembled systems formed of micelles or vesicles have frequently been discussed as model systems for self-healing materials because their structure is dictated by thermodynamics and hence they quickly restore upon perturbation. In this aspect, they mimic many natural systems such as biological cells. However, in contrast to most synthetic...conference paper 2013

Liu, Z. (author), Besseling, N.A.M. (author), Mendes, E. (author), Picken, S.J. (author)Polyborosiloxanes (PBSs) are viscoelastic, transparent, colourless, self-healable polymer matrices, synthesized by reacting linear polydimethylsiloxanes (PDMSs) with boric acid (BA) above 150°C. BA takes part not only in cleaving the PDMS chains, but also contributes boronic-acid like moieties to the cleaved chain ends, which provide...conference paper 2013

Van de Krol, R. (author), Ségalini, J. (author), Enache, C.S. (author)The properties of thin film InVO4 photoanodes for water splitting have been studied. Compact films of InVO4 were prepared by spray pyrolysis and are found to be stable between pH 3 – 11. Although the indirect bandgap is 3.2 eV, a modest amount of visible light absorption is observed. The origin of this absorption is attributed to the presence of...conference paper 2010

Sousa, F.S. (author), Portela, L.M. (author), Mudde, R.F. (author), Mangiavacchi, N. (author)We present a method for fully-resolved simulations of bubbly flows using a front-tracking/front-capturing technique. The method is a modification of a marker-and-cell method developed previously for free-surface flows. The basic approach is somehow similar to the front-tracking method of Tryggvason: the continuity and Navier-Stokes equations are...conference paper 2006
