The presented work consists of the presentation and discussion of unsteady experimental results of controlled vibration measurements for two single-blade and two cluster test cases subjected to the same subsonic flow conditions. The experiments were perfor ...
The damping behavior of bent fiber near-field scanning optical microscopy (NSOM) probes operating in tapping mode oscillation is investigated in air and water. We show that the significant drop in probe quality factor Q, which occurs at the air-water inter ...
The prediction of flutter and forced response at normal flow conditions has become a standard procedure during the design of compressor airfoils. But at severe off-design conditions, the flow field becomes very complex, especially during the surge blow-dow ...
The mid-infrared range is of interest in spectroscopic applications, due to the large number of organic compounds that exhibit characteristic absorption bands in this spectral region. Semiconductor technology, however, has been developed mainly for the nea ...
The present thesis is an advanced contribution to the design process of large synchronous generators with high number of poles. It proposes two original contributions, the first one allowing a very precise prediction of the no-load voltage and of the no-lo ...
This paper reports on the results of recent experiments performed on the JET tokamak on toroidal Alfven eigenmodes (TAEs) with toroidal mode number (n) in the range up to vertical bar n vertical bar = 7. The stability properties of these medium-nTAEs are i ...
Since sustainability and environmental issues rose lately, lightweighting has been the point of interest for automotive and aerospace sectors. Lightweighting reduces the fuel consumption of the vehicles and as a result of this reduces emissions. Aluminum, ...
We present a detailed comparison of the rheology of concentrated hard and soft-sphere suspensions using a variety of techniques including large-amplitude oscillatory shear (LAOS). While the soft spheres are jammed and exhibit permanent contact, the hard-sp ...
The modeling of snow redistribution in turbulent conditions plays an important role for the prediction of snow accumulation and avalanche risk. For this aim two Lagrangian models, one for the suspension and one for the saltation of snow were coupled. The s ...
We investigate in detail the problem of confined pressure-driven laminar flow of neutrally buoyant non-Brownian suspensions using a frictional rheology based on the recent proposal of Boyer et al. (Phys. Rev. Lett., vol. 107 (18), 2011, 188301). The fricti ...
