As the urge to decarbonise the energy field becomes increasingly important, a growing interest is shown in wind turbine technologies. In particular, the past few years have seen the development of floating offshore wind turbines for applications in deep waters.<br/><br/>In addition to the harsher environment they are facing, these wind turbines...

Atmospheric delay has a profound impact on synthetic aperture radar (SAR) interferometry, inducing a spatial signal that significantly devaluates interferometric products. While the wide-scale variability of the atmosphere can be adequately modeled with global or regional weather models, it is especially the turbulent and convective part of the...

We present and evaluate a two-phase model for Eulerian large-eddy simulations (LES) of liquid-fuel injection and mixing at high pressure. The model is based on cubic equations of state and vapor-liquid equilibrium calculations and can represent the coexistence of supercritical states and multi-component subcritical two-phase states via a...

Large-eddy simulations of a Lagrangian transition from a vertically well-mixed stratocumulus-topped boundary layer to a situation in which shallow cumuli penetrate an overlying layer of thin and broken stratocumulus are compared with aircraft observations collected during the Atlantic Stratocumulus Transition Experiment. Despite the complexity...

Modeling of scalar transport is an essential point in the simulation of non-premixed turbulent combustion. The fuel and oxidizer streams are, in general, modeled with an equation for the mixture fraction Z. This mixture fraction is a bounded function, i.e. it can never become large than one or smaller than zero. Symmetric central differencing...

Large Eddy Simulation (LES) is now recognized as an efficient numerical tool to predict gaseous combustion in industrial burners, and a number of examples of applications can be found in the literature. In these examples, the accuracy and the predictive capacity of LES are clearly demonstrated, even for unsteady phenomena. However most...

In the present study, aerodynamic noise from a forward-facing step is numerically investigated for Reynolds number based on the step height, Reh=8,000 and flow Mach number, M=0.03. A three-dimensional flow over the forward-facing step is calculated by the incompressible large eddy simulation (LES), while its acoustic field is solved by the...

Despite significant advances in understanding and modelling of combustion-LES, LES of premixed combustion remains a challenging issue. This problem is more challenging when an incompressible formulation is used where the density coupling is weak, and an improper density coupling can lead to unrealistic flame speeds and thickness. For this...

All aircraft shed, as a consequence of lift, a wake ("vorticity sheet") which rapidly rolls up into several concentrated vortices at a distance of a few chords behind the trailing edge of the wing. A simplified configuration has been adopted to understand the physical mechanisms characterizing the merging process in the extended near-field. This...
