The flow over airfoils that experience separation of the trailing edge type becomes three-dimensional at angles of attack around maximum lift and Stall Cells (SCs) form. SCs are large scale coherent structures of separated flow that consist of two counter-rotating vortices. In the present study the turbulence structure of a SC over a rectangular...

Inherent physical uncertainties can have a significant influence on computational predictions. It is therefore important to take physical uncertainties into account to obtain more reliable computational predictions. The Galerkin polynomial chaos method is a commonly applied uncertainty quantification method. However, the polynomial chaos...

Background: Working together on room for growth and sustainability in the Port of Rotterdam is increasing while space in the area is limited. Furthermore the Port is in the vicinity of cities that want to grow while citizens want to live in an environment that is safe, clean and with good quality for living. The Port of Rotterdam therefore needs...

The objective of this work is to develop a search site to map all of High Education Institutions (HEI) and their environmental actions; to create a worldwide cooperation network between HEI with practical support in its campuses. The Site will have the following workflow: first, the HEI is invited to take part on the network, when one...

Radar cross section prediction techniques are used to determine the radar signature of a military platform when the radar signature can not be determined experimentally, because the platform is not available or for reasons of time and cost. For classic jet aircraft the radar cross section for forward observation angles is dominated by the...

MCTS has been successfully applied to many sequential games. This paper investigates Monte Carlo Tree Search (MCTS) for the simultaneous move game Tron. In this paper we describe two different ways to model the simultaneous move game, as a standard sequential game and as a stacked matrix game. Several variants are presented to adapt MCTS to...

The outcomes of a preliminary experimental programme into a gel-based healing system that allows immediate healing of cementitious materials followed by longerterm development of robust healing through biological processes are reported. Alginate gels protect and maintain the viability of encapsulated microorganisms and have been used for...

Much attention has been paid to bilateral negotiation in which the dispute is between only two parties. However, automated multilateral negotiation in which more than two negotiating parties need to reach a joint agreement, has received relatively less attention, even though such negotiations are required in many circumstances (e.g. a group of...

In this work we present and solve a class of non--Newtonian viscoelastic fluid flow problems. Models for non-Newtonian fluids can be classified into three large groups depending on the type of the constitutive relation used: algebraic, differential and integral. The first type of models are most simple one, the last are the most physically...

A Multidisciplinary Design Optimization (MDO) system for a wing with nacelle and pylon is developed. The present MDO system is based on the integration of Computational Fluid Dynamics (CFD) codes and NASTRAN based an aeroelastic-structural interface code. The Kriging model is employed to save the computational time of objective function...

General Aviation safety is a pressing concern. In this research, we consider the factor that appears most often in accidents: the pilot. Newly-licensed pilots can fly without their instructor, potentially as the only or most experienced pilot in the aircraft. Commercial debrief products use technology in the flight deck to collect data and...

Nonlinear acoustic waves have many applications in very different fields of industry. The problem considered in this work consists of predicting the behaviour of gas filling a one dimensional tube when suffering the action of very high frequency waves. The numerical technique applied to solve this problem is a third order finite volume method...

Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first...

Since late 1990’s, micron-resolution particle image velocimetry (?PIV) has been widely developed to measure fluid flow velocities field in microchannels [1]. While 2D ?PIV method has been extensively investigated, accurate 3D ?PIV still remains challenging to implement since it usually requires specialized and expensive equipments (e.g. confocal...

Designing challenges engineers to develop both economically attractive and safe designs. This might seem a paradox, but with the application of the observational method, wherein safety is checked by real-time monitoring, economic design and safety are united. The observational method is recently successfully applied in the Netherlands during the...

We have extended the complex Jacobi iteration to simulate nonlinear optical components. The size of these components is comparable to the used wavelength (µm). In this paper we will give an overview of the technique and several simulation results. The algorithm uses a central difference analogue of the Helmholtz equation. The used nonlinearity...

A new lifting bridge is being constructed crossing the river Oude Maas in the Rotterdam harbour area in the Netherlands. Since foundation deformations of the main piers have a large influence on the performance of the superstructure, extensive deformation analyses have been performed during the design phase. In order to minimise the risks and...

Within the theme ‘Self-healing materials for prolonged lifetime’ (NMP.2012.2.1-3) of the Seventh Framework Programme, self-healing concrete is an important topic. The project HEALCON, which deals with self-healing concrete to create durable and sustainable concrete structures, is funded by EU-FP7 and started in January 2013. The coordinator of...
