Loh, K.K.L. (author), Shoeibi Omrani, P.S. (author), van der Linden, R.J.P. (author)The prediction of the gas production from mature gas wells, due to their complex end-of-life behavior, is challenging and crucial for operational decision making. In this paper, we apply a modified deep LSTM model for prediction of the gas flow rates in mature gas wells, including the uncertainties in input parameters. Additionally, due to...article 2018

Zondag, H.A. (author), de Boer, R. (author), Smeding, S.F. (author), van der Kamp, J. (author)A 140 l lab scale shell-and-tube PCM heat storage was built and tested, and the experimental results were compared to a numerical model. Natural convection in the PCM was found to significantly influence the local temperature distribution in the storage vessel, which could not be predicted well by the model, since the model assumes only...article 2018

Candela, T. (author), Wassing, B. (author), Heege, J.T. (author), Buijze, L. (author)The sustainability of geothermal fields is based on a paradox. On one side, fractures are targeted on heat-flow improvement, and on the other side, the same fractures are avoided because of induced seismicity risk. In this context, we developed analytical approaches for estimating (1) thermo–poro-elastic stresses in a fractured geothermal system...article 2018

(author)Membrane distillation is an attractive technology for production of fresh water from seawater. The MemPower® concept, studied in this work, uses available heat (86 °C) to produce pressurized water (2.2 bar and 46 °C) by membrane distillation, which again can be used to power a turbine for co-production of electricity. We develop a non...article 2017

Theelen, M. (author), Beyeler, K. (author), Steijvers, H. (author), Barreau, N. (author)Unencapsulated CIGS solar cells were simultaneously exposed to either dry or damp heat combined illumination. In-situ monitoring of their electrical parameters demonstrated a rapid decrease of the efficiency for the solar cells exposed to damp heat plus illumination. This decrease was mainly driven by changes in the shunt resistances, affecting...article 2017

Jacobs, P. (author), Borsboom, W.A. (author)Recirculation hoods equipped with carbon and plasma filters are becoming more and more popular. The aim of this study is to determine the effectiveness of recirculation hoods with regard to PM2 5 and NOx removal in a 26 m3 lab kitchen with a gas furnace. With the carbon filter PM2 5 is reduced for about 30%. A fresh carbon filter removed about...conference paper 2017
