Multiscale Computational Methodology Applied to Hydroacoustic Resonance in Cavitating Pipe Flow

Nicolas Ruchonnet

The present work is a contribution to the physical analysis and numerical simulation of the pressure surges in hydraulic machinery and connected conduit systems. Localized hydrodynamic instabilities including cavitation are prone to interact with the entir ...

Physical and numerical modeling of harbors and shore protection measures / Modélisation physique et numérique de mesures de protection portuaires et d’aménagement de plages

Azin Amini, Fadi Hachem

The expansion project of the ‘’Port de la Nautique’’ and the creation of adjacent new beaches on the ‘’Lac Léman’’ in Geneva is currently under survey. In the conceptual and study phase, numerical- and physicalscaled models have been exploited at the Ecole ...

Glaucoma is one of the leading causes of blindness in the world. It results in an increase of the aqueous humour (AH) outflow pathway which leads to an increase of the intraocular pressure (IOP). Many treatments exists to reduce and stabilize the IOP such ...

Effect of nonuniform boundary conditions on steady flow in saturated homogeneous cylindrical soil columns

David Andrew Barry

Laboratory column experiments involving steady flow in homogeneous soil are often analyzed assuming that the flow is spatially uniform in any plane transverse to the longitudinal axis aligned with the column centerline. Axisymmetric steady flow in such a c ...

Large-Scale PIV surface flow measurements in shallow basins with different geometries

Anton Schleiss, Sameh Ahmad Kantoush

Shallow depth flow fields and low velocity magnitudes are often challenges for traditional velocity measuring instruments. As such, new techniques have been developed that provide more reliable velocity measurements under these circumstances. In the presen ...

Influence of inlet boundary conditions on the local haemodynamics of intracranial aneurysms

Nikolaos Stergiopoulos, Philippe Reymond

Haemodynamics is believed to play an important role in the initiation, growth and rupture of intracranial aneurysms. In this context, computational haemodynamics has been extensively used in an effort to establish correlations between flow variables and cl ...

Large-eddy simulation of a mildly curved open-channel flow

Koen Blanckaert

After validation with experimental data, large-eddy simulation (LES) is used to study in detail the open-channel flow through a curved flume. Based on the LES results, the present paper addresses four issues. Firstly, features of the complex bicellular pat ...

Cambridge University Press2009

In this work a quasi-analytical physical model for the accurate prediction of the potential of GAA nanowire transistors with an arbitrary regular polygon as a cross section is developed. Two case studies concerning triangular and square cross-sections are ...
