Assaad, W. (author), Pasaribu, H.R. (author), Zijsling, DJ (author), van Dalen, K.N. (author), Metrikine, A. (author)Shell has developed a novel monodiameter well concept for oil and gas wells as opposed to the traditional telescopic well design. A Mono diameter well contains multiple casing sections with the same internal diameter. This is achieved by expansion of the casing sections concerned using an expansion cone. Since the well is drilled in stages and...conference paper 2017

Fernandes, O. (author), Blom, D.S. (author), Frey, S. (author), Van Zuijlen, A.H. (author), Bijl, H. (author), Ertl, T. (author)We present an integrated insitu visualization approach for partitioned multiphysics simulation of fluidstructure interaction. The simulation itself is treated as a black box and only the information at the fluidstructure interface is considered, and communicated between the fluid and solid solvers with a separate coupling tool. The...conference paper 2015

Blom, D.S. (author), Van Zuylen, A.H. (author), Bijl, H. (author)Strongly coupled partitioned fluidstructure interaction problems require multiple coupling iterations per time step. The fluid domain and the structure domain are solved multiple times in each time step such that the kinematic and dynamic interface conditions on the fluidstructure interface are satisfied. QuasiNewton methods have been...conference paper 2014

Scholcz, T.P. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)The focus of this paper is on acceleration of strong partitioned coupling algorithms for fluidstructure interaction. Strong partitioned coupling requires the solution of a coupled problem at each time step during the simulation. Hereto, an interface residual is defined such that the kinematic and dynamic interface conditions on the fluid...conference paper 2012

Coarse level NewtonKrylov acceleration of subiterations in partitioned fluidstructure interactionVan Zuijlen, A.H. (author), Bijl, H. (author)Computational fluidstructure interaction is commonly performed using a partitioned approach. For strongly coupled problems subiterations are required, increasing computational time as flow and structure have to be resolved multiple times every time step. Reductions in computing times can be achieved by e.g. improving the convergence of the sub...conference paper 2011

Scholcz, T.P. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)High fidelity analysis of fluidstructure interaction systems is often too timeconsuming when a large number of model evaluations are required. The choice for a solution procedure depends often on the efficiency of the method and the possibility of reusing existing field solvers. Aggressive SpaceMapping, a technique originally developed for...conference paper 2011

Kreeft, J.J. (author), Weghs, M. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)Two reduced order models are presented for the simulation of physically strong coupled fluidstructure interaction problem, based on computationally partitioned flow and structure solvers. The reduced order models used are a class of quasiNewton coupling methods to obtain a stable solution and to reduce the number of subiterations. The second...conference paper 2011

Sterenborg, J.J.H.M. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)In order to validate fluidstructure interaction solvers, a one degree of freedom (1 DOF) aeroelastic experiment is performed. A rigid wing with an harmonically actuated flap, is suspended by springs to allow a free heaving motion. Displacements and time dependent aerodynamic forces are measured for reduced flap frequencies ranging from k = 0.1...conference paper 2011

Michler, A.K. (author), Dwight, R.P. (author), Heinrich, R. (author)The accurate prediction of the aerodynamic coefficients under cruise conditions is of major importance for assessing the aircraft’s fuel consumption. To this end, fluid dynamics, structural mechanics and flight mechanics have to be considered: on the one hand, the structure elastically deforms under the influence of the flow and a state of...conference paper 2009

Witteveen, J.A.S. (author), Bijl, H. (author)A robust and efficient uncertainty quantification method is presented for resolving the effect of uncertainty on the behavior of multiphysics systems. The extrema diminishing method in probability space maintains a bounded error due to the interpolation of deterministic samples at constant phase in a transonic airfoil flutter problem.conference paper 2009

Witteveen, J.A.S. (author), Bijl, H. (author)An explicit mesh motion algorithm based on inverse distance weighting interpolation is presented. The explicit formulation leads to a fast mesh motion algorithm and an easy implementation. In addition, the proposed pointbypoint method is robust and flexible in case of large deformations, hanging nodes, and parallelization. Mesh quality results...conference paper 2009

Wendland, H. (author)This paper gives a survey on kernelbased scattered data interpolation methods in the context of static aeroelastic computations. We describe the general procedure, address problems and solutions for largescale data sets, for flat data sets, and for rotational information. Finally, we demonstrate the versatility of the method by showing two...conference paper 2006

Murea, C.M. (author), Vazquez, C. (author)We study the fluidstructure coupled problem between an incompressible fluid and an elastic curved arch. The fluid flow is modeled by 2D steady Stokes equations with normal velocity boundary condition on the curved interface and the arch verifies a particular 1D case of the thin shell theory of Koiter. We present an optimal control formulation...conference paper 2006
