Turbulent flow in and over an urban canopy in Vancouver, Canada

In this Master’s thesis, turbulent flow of the atmosphere over the urban canopy of the ‘Sunset’ neighbourhood in Vancouver was studied using a Large Eddy Simulation (LES) model. A high precision Light Detection and Ranging (LiDAR) dataset was employed to r ...

Hydrodynamics of turbulent flows within arrays of circular cylinders

Ana Margarida Da Costa Ricardo

In rivers riparian vegetation can have not only strong interaction with the flow but also with the ecological services of the aquatic system. In wetlands and along riverbanks often tree-like vegetation with quite stiff trunks can be found. The study of the ...

Experimental and Numerical Assessment of the Aeroelastic Stability of Blade Pair Packages

Peter Ott, Achim Zanker

The stabilizing effect of grouping rotor blades in pairs has been assessed both, numerically and experimentally. The bending and torsion modes of a low aspect ratio high speed turbine cascade tested in the non-rotating test facility at EPFL (Ecole Polytech ...

An adjoint-based approach to the optimal control of separated flows

Edouard Boujo

Flow separation is relevant to many industrial applications, since it is detrimental to the aerodynamic performance of vehicles, induces vibrations in mechanical structures, but can also contribute to improve mixing in combustion devices. In this thesis, t ...

The impact of variable building height on drag, flow and turbulence over a realistic suburban surface

Marc Parlange, Marc Calaf Bracons, Marco Giovanni Giometto, Andreas Christen

In realistic urban environments, where buildings experience variable heights, the tallest structures have a disproportional impact on drag, mean flow and turbulence. Although wind-engineering studies document well the effects of individual high-rise buildi ...

Determination of External Forces in Alpine Skiing Using a Differential Global Navigation Satellite System

Julien Chardonnens

In alpine ski racing the relationships between skier kinetics and kinematics and their effect on performance and injury-related aspects are not well understood. There is currently no validated system to determine all external forces simultaneously acting o ...

Turbulent flow within a random array of rigid, emergent stems : Laboratory characterization of the drag coefficient

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Ana Margarida Da Costa Ricardo

Within the bioengineering framework, designing a non-erodible channel is a complex fluid dynamics problem as it involves knowing the drag exerted on the boundary, the drag exerted on the plant stems and the overall friction slope. Most of the existing desi ...

Global modes in a confined impinging jet: application to heat transfer and control

Philippe Meliga

We investigate the stability and control of a plane, laminar jet impinging on a flat plate in a channel, a geometry used to cool down a hot wall with a cold air jet in many industrial configurations. The global stability analysis indicates that, even for a ...

Forces exerted by a correlated fluid on embedded inclusions

Anne-Florence Raphaëlle Bitbol

We investigate the forces exerted on embedded inclusions by a fluid medium with long-range correlations, described by an effective scalar field theory. Such forces are the basis for the medium-mediated Casimir-like force. To study these forces beyond therm ...
