Jacobs, P. (author)In dit artikel wordt specifiek ingegaan op de Nederlandse regelgeving voor kachels en open haarden en tevens een vergelijking gemaakt met de buitenlandse regelgeving. Nederland blijkt in Europa nogal achter te lopen wat betreft regelgeving voor fijnstofemissie vanuit houtstook. In 2022 wordt Europese regelgeving van kracht, die helaas niet gaat...article 2017

van Leeuwen, C.J. (author), Yildirim, K.S. (author), Pawelczak, P. (author)Wireless Power Transfer (WPT) technologies aim at getting rid of cables used by consumer devices for energy provision. As long distance WPT is becoming mature, the health impact of WPT becomes increasingly important to consider. In this paper we look at how to maximize the wireless power transfer to remote devices, while maintaining a safe level...conference paper 2017

Smits, E.C.P. (author), Walter, A. (author), de Leeuw, D.M. (author), Asadi, K. (author)Transfer of graphene and other two-dimensional materials is still a technical challenge. The 2D-materials are typically patterned after transfer, which leads to a major loss of material. Here, we present laser induced forward transfer of chemical vapor deposition grown graphene layers with well-defined shapes and geometries. The transfer is...article 2017

Könst, P.M. (author), Hernandez Mireles, I. (author), van der Stel, R.W. (author), van Os, P.M (author), Goetheer, E.L.V. (author)In view of its promise as sustainable process for CO2 capture and its potential in the production of feed, food and natural high value products such as omega-3 fatty acids and anti-oxidants such as astaxanthin, large scale algae cultivation is gaining commercial interest. Currently, most systems are based on directly contacting CO2 containing...article 2017

(author), Loeve, D. (author)This paper presents the results of a study into the functional requirements and optimisation of the CO2 shipping chain, with a focus on the offshore offloading system. The goal was to evaluate the feasibility of a generic approach to the development of ship-based CO2 transport and storage systems in the North Sea, using a range of typical North...article 2017

Belfroid, S.P.C. (author)This report forms part of the deliverables for project 060.25718, which is a TNO assignment by RWS. The goal of the project is to review currently used screening methodologies and input as used by RWS and Deltares for screening purposes of designs of gates and valves. The first main deliverable was a workshop as held at TNO (Delft) on 24 Jan...report 2017

Sanna, F. (author), Golliard, J. (author), Belfroid, S.P.C. (author)Damping in pipes quantifies the attenuation of the pressure amplitude due to losses. Applications with mixtures of two immiscible phases are common but limited studies on damping with multiphase flows in pipes are available. The purpose of this work is to describe the setup as well as the post-processing used to quantify the acoustical damping...conference paper 2016

van 't Westende, J.M.C. (author), Shoeibi Omrani, P. (author), Vercauteren, F.F. (author), Nennie, E.D. (author)Foam assisted lift is a deliquification method in the oil and gas industry, which aims to prevent or postpone countercurrent gas-liquid flow in maturing gas wells or to assist in removing downhole accumulated liquids. According to Nimwegen, who performed experiments with foam flows, foam accomplishes this, since the creation of foam postpones...conference paper 2016

Jacobs, P. (author)Het binnenklimaat in basisscholen en kinderdagverblijven is al jaren een aandachtspunt. Ondanks alle aandacht constateren GGD, VLA en TNO dat er nog steeds veel mis gaat met ventilatie. Om dat probleem aan te pakken hebben de VLA en TNO tools ontwikkeld om het onderhoud te waarborgen.article 2016

Polinder, H. (author)In een divers aantal regio’s in het land beschikt Nuon over warmtenetten waarmee woningen en utiliteitsgebouwen worden voorzien van warmte. Voor deze warmtenetten heeft Nuon een CO2-reductiemodel opgesteld, in de vorm van een Excel rekentool. Hiermee wordt ten opzichte van een referentiesituatie berekend hoeveel CO2 er minder wordt uitgestoten...report 2016

van der Ham, L.V. (author), Khakharia, P.M. (author), Goetheer, E.L.V. (author)A novel type of separating heat exchanger, called a heat-integrated liquid-desorption exchanger (HILDE), applied to a typical CO2 desorption process, has been investigated both numerically and experimentally. Process simulations, hydrodynamic and mass transfer experiments, and a preliminary cost evaluation have been used to compare HILDE to the...conference paper 2016

Violato, D. (author), Belfroid, S.P.C. (author), Lee, J.S. (author)In this work, the acoustic effects of horizontal airwater flow through an orifice are investigated experimentally. Single phase flow (air) and two-phase flow (air and water) tests are performed for two sets of orifices. One set of straight edged and one set of upstream rounded orifices. For each set, the diameters of the orifices were 2, 5, and...conference paper 2016

Belfroid, S.P.C. (author), Nennie, E.D. (author), van Wijhe, A. (author), Pereboom, H.P. (author), Lewis, M. (author)Piping structures are generally subjected to high dynamic loading due to multiphase forces. In particular subsea structures are very vulnerable as large flexibility is required to cope for instance with thermal stresses. The forces due to multiphase flow are characterized by a broadband spectrum with high amplitudes. These forces differ with...conference paper 2016

(author)Uncertainty plays a significant role in the Benchmark on the Aerodynamics of a Rectangular Cylinder (BARC) with a chord-to-depth ratio of 5. In particular, besides modeling and numerical errors, in numerical simulations it is difficult to exactly reproduce the experimental conditions due to uncertainties in the set-up parameters, which sometimes...article 2016

Dwight, R.P. (author), Desmedt, S.G.L. (author), Shoeibi Omrani, P. (author)Propagation of random variables through computer codes of many inputs is primarily limited by computational expense. The use of sparse grids mitigates these costs somewhat; here we show how Sobol indices can be used to perform dimension adaptivity to mitigate them further. The method is compared to conventional adaptation schemes on sparse grids...bookPart 2016
