Skandali, M. (author), Jansen, K.M.B. (author), Koussios, S. (author), Sinke, J. (author), Benedictus, R. (author)The purpose of this study is to simulate the two-dimensional, transient and continuous heat transfer during the thermoset Automated Tape Laying (ATL) process. The heat transfer analysis is coupled with a cure kinetics model of the thermoset prepreg tapes used for the process. Unlike most studies, the process is modelled in a Lagrangian framework...conference paper 2015

Lelieveld, C. (author), Jansen, K.M.B. (author)A composite structure consisting of a Shape Memory Polymer (SMP) matrix and three Shape Memory Alloy (SMA) strips was constructed. The SMA strips act as actuators which create forward and backward angle bends of 90 degrees of the composite structure. The function of the polymer matrix was to give the structure enough stiffness. During the...conference paper 2013

Fatemi, S.A. (author), Jansen, J.D. (author), Rossen, W.R. (author)An enhanced-oil-recovery pilot test has multiple goals, among them to verify the properties of the EOR agent in situ. Given the complexity of EOR processes and the inherent uncertainty in the reservoir description, it is a challenge to discern the properties of the EOR agent in situ. We present a simple case study to illustrate this challenge: a...conference paper 2015

Akram, M. (author), Bhowmik, S. (author), Jansen, K.M.B. (author), Ernst, L.J. (author)It is noted that in search of long term and efficient service performance in the context of future generation of aerospace materials, there is increasing need of metal-high performance polymer composite. Based on these considerations, high temperature resistant polymeric sheet such as Polyimide Meldin7001 sheet, is joined with Titanium sheet by...conference paper 2011

Van Doren, J. (author), Markovinovic, R. (author), Jansen, J.D. (author)During the design of development concepts for the exploitation of oil and gas reservoirs, frequent use is made of numerical simulation of the flow of multi-phase fluids through porous rock. Recently, increased attention has been paid to systematic optimization of well positions and operating parameters (rates, pressures) over the life of the...conference paper 2006

Van der Meer, J.M. (author), Van Odyck, D.E.A. (author), Wirnsberger, P. (author), Jansen, J.D. (author)If secondary hydrocarbon recovery methods fail because of the occurrence of gravity override or viscous fingering one can turn to an enhanced oil recovery method like the injection of foam. The generation of foam can be described by a set of partial differential equations with strongly nonlinear functions, which impose challenges for the...conference paper 2014

Jansen, K.M.B. (author)During the molding process residual stresses are formed due to thermal contraction during cooling as well as the local pressure history during solidification. In this paper a simple analytical model is reviewed which relates residual stresses, product shrinkage as well as warpage to the temperature and pressure histories during molding. Precise...conference paper 2015

Jansen, R.J. (author), Van Egmond, R. (author), De Ridder, H. (author), Silvester, S. (author)Operational police work can be characterized by the continuous switching between surveillance, responding to incidents, and office activities. Transitions between these activities are initiated by radio contact, messages on a mobile data terminal, or personal observations. The “information environment” emerging from these channels may cause...conference paper 2013

Kahrobaei, S. (author), Mansoori, M. (author), Joosten, G.J.P. (author), Van den Hof, P.M.J. (author), Jansen, J.D. (author)It is well known that parameter updating of large-scale numerical reservoir flow models (a.k.a. ‘computer assisted history matching’) is an ill-posed inverse problem. Typically the number of uncertain parameters in a reservoir flow model is very large whereas the available information for estimating these parameters is limited. The classic...conference paper 2014
