Formation flying is introduced as a new and innovative air transportation system for long-haul commercial flight. With this paper the operational feasibility of formation flying is addressed, both from a market demand and economic, as well as an air traffic control perspective. Preliminary results of a case study indicate that operating a newly...

Effect of viscoelasiticity on the far-dissipation range of homogeneous isotropic turbulence

Nguyen, M.Q. (author), Simöens, S. (author), Delache, A. (author), El Hajem, M. (author), Bos, W. (author), Poole, R. (author)

The comparison of the results of direct numerical simulations of isotropic turbulence of Newtonian and viscoelastic fluid, based on the FENE-P model, provide evidence that viscoelasticity modifies qualitatively the behavior of the smallest scales: we observe a k⁻⁶ law in the far dissipation range of the energy spectrum and we show...

Fusion of Plans in a Framework with Constraints

De Weerdt, M.M. (author), Bos, A. (author), Tonino, J.F.M. (author), Witteveen, C. (author)

The promise of multi-agent systems is that multiple agents can solve problems more efficiently than single agents can. In this paper we propose a method to implement cooperation between agents in the planning phase, in order to achieve more cost-effective solutions than without cooperation. Two results are presented: First of all, we introduce a...

Angular statistics of lagrangian trajectories

Bos, W. (author), Kadoch, B. (author), Schneider, K. (author)

The angle between subsequent particle displacement increments is evaluated as a function of the timelag in isotropic turbulence. It is shown that the evolution of the average of this angle contains two well-defined power-laws, reflecting the multi-scale dynamics of high-Reynolds number turbulence.

Direction change of fluid particles in confined two-dimensional turbulence

The directional change of a fluid particle can be measured by the angle between two subsequent particle displacement increments. At small values of the time-increment the so-defined angle is proportional to the curvature of the trajectory. At large values this coarse-grained curvature should be affected by the presence of solid no-slip walls...

Temperature fluctuations induced by frictional heating in isotropic turbulence

The temperature fluctuations generated by viscous dissipation in an isotropic turbulent flow are studied using direct numerical simulation. It is shown that the scaling of their variance with Reynolds number is at odds with predictions from recent investigations. The origin of the discrepancy is traced back to the anomalous scaling of the...

Surgical Quay-wall Renovation

Bos, J.W. (J.Bos@royalhskoning.com) (author), Winde, S.C. (sc.winde@portofrotterdam.com) (author)

This paper describes an innovative approach towards quay wall renovation design. In the “RDM Kraanbaan 13” project in Rotterdam, significant cost savings were made and environmental impact was minimised, while on a tight schedule and with limited information about the structure and its future use. Essential were a very practical and flexible...

Importance sampling of severe wind gusts

Bos, R. (author), Bierbooms, W.A.A.M. (author), Van Bussel, G.J.W. (author)

An important problem that arises during the design of wind turbines is estimating extreme loads with sufficient accuracy. This is especially difficult during iterative design phases when computational resources are scarce. Over the years, many methods have been proposed to extrapolate extreme load distributions from relatively short time series...

Robust estimation of the noise variance from background MR data

Sijbers, J. (author), Den Dekker, A.J. (author), Poot, D. (author), Bos, R. (author), Verhoye, M. (author), Van Camp, N. (author), Van der Linden, A. (author)

In the literature, many methods are available for estimation of the variance of the noise in magnetic resonance (MR) images. A commonly used method, based on the maximum of the background mode of the histogram, is revisited and a new, robust, and easy to use method is presented based on maximum likelihood (ML) estimation. Both methods are...

Integrated Design of a Long-Haul Commercial Aircraft Optimized for Formation Flying

The airline industry is under continuous pressure to reduce emissions and costs. This paper investigates the feasibility for commercial airlines to use formation flight to reduce emissions and fuel burn. To fly in formation, an aircraft needs to benefit from the wake vortices of the preceding aircraft. This requires a stable aerodynamic flow,...
