Edeling, W.N. (author)The goal of this thesis is to make predictive simulations with Reynolds-Averaged Navier-Stokes (RANS) turbulence models, i.e. simulations with a systematic treatment of model and data uncertainties and their propagation through a computational model to produce predictions of quantities of interest with quantified uncertainty. To do so, we make...doctoral thesis 2015

New estimates of potential impacts of sea level rise and coastal floods in Poland (discussion paper)Paprotny, D. (author), Terefenko, P. (author)Polish coastal zone is thought to be of the most exposed to sea level rise in Europe. With climate change expected to raise mean sea levels between 26 and 200 cm by the end of the century, and storms increasing in severity, accurate estimates of those phenomena are needed. Recent advances in quality and availability of spatial data in Poland...journal article 2015

Roebroeks, J. (author), Eftekhari, A.A. (author), Farajzadeh, R. (author), Vincent-Bonnieu, S. (author)Foam flooding as a mechanism to enhance oil recovery has been intensively studied and is the subject of multiple research groups. However, limited stability of surfactant-generated foam in presence of oil and low chemical stability of surfactants in the high temperature and high salinity of an oil reservoir are among the reasons for foam EOR not...conference paper 2015

Jones, S.A. (author), Van der Bent, V. (author), Farajzadeh, R. (author), Rossen, W.R. (author), Vincent-Bonnieu, S. (author)Aqueous foams are a means of increasing the sweep efficiency of enhanced oil recovery processes. An understanding of how a foam behaves in the presence of oil is therefore of great importance when selecting suitable surfactants for EOR processes. The consensus is currently that the most reliable method for determining the foam behavior in the...conference paper 2015

Baviskar, S.M. (author), Heimovaara, T.J. (author)We believe the unsaturated and heterogeneous nature of landfills leads to the emergence of preferential pathways of water and dissolved compounds through the waste body. In this research we explore the origin of preferential flow in a porous media with a deterministic numerical model. In this model water flow is modeled with the Richards’...conference paper 2015

Sagliano, M. (author), Oehlschlagel, T. (author), Theil, S. (author), Mooij, E. (author)One of the most powerful analysis tools to deal with entry guidance problems is the possibility to formulate them as optimal control problems (OCPs). Environmental constraints, actuator limits, and strict requirements on the final conditions can be efficiently transcribed, resulting in a discrete, finite-dimension nonlinear programmming (NLP)...conference paper 2015

Mei, X. (author), Dai, Z. (author), Van Gelder, P.H.A.J.M. (author), Gao, J. (author)The magnitude of anthropogenic influence, especially dam regulation, on hydrological system is of scientific and practical value for large river management. As the largest dam in the world by far, Three Gorges Dam (TGD) is expected to be a strong evidence on dam impacts on downstream hydrological regime. In this study, statistical methods are...journal article 2015

Tol, H.J. (author), De Visser, C.C. (author), Van Kampen, E.J. (author), Chu, Q.P. (author)This paper presents a study on fault tolerant flight control of a high performance aircraft using multivariate splines. The controller is implemented by making use of spline model based adaptive nonlinear dynamic inversion (NDI). This method, indicated as SANDI, combines NDI control with nonlinear control allocation based on an onboard...conference paper 2015

Brink, E. (author), Gerber, M. (author), De Boer, A. (author), Van der Geest, M. (author), Zeilstra, D. (author)Starter/generator units based on PM machines are generally not considered due to their inherent safety risks. This technology can, however, prove advantageous for aerospace applications where mass, volume, efficiency and low maintenance costs play a significant role. A safety analysis is performed in order to identify the safety and mitigation...conference paper 2015

Alakhramsing, S. (author), Van Ostayen, R.A.J. (author), Eling, R.P.T. (author)Accurate prediction of cavitation is an important feature in hydrodynamic bearing modeling. Especially for thermo-hydrodynamic modeling, it is crucial to use a mass-conservative cavitation algorithm. This paper introduces a new mass-conserving Reynolds cavitation algorithm, which provides fast convergence and easy implementation in finite...journal article 2015

(author)Agave syrup is a fermentable by-product from the Agave industry that is used for pulque production, a typical Mexican fermented beverage. However, to date, the information available on its physicochemical composition is scarce, with this study being one of the first contributions on the subject. Here the influence of thermal treatment at 121ºC...journal article 2015
