Fractal Modelling And Analysis Of Flow-Field Images

Michaël Unser, Ricard Delgado Gonzalo, Pouya Dehghani Tafti

We introduce stochastic models for flow fields with parameters that dictate the scale-dependent (self-similar) character of the field and control the balance between its rotational vs compressive behaviour. The development of our models is motivated by the ...

Scalar dispersion in strongly curved open-channel flows

Koen Blanckaert

Large-eddy simulations (LES) and Reynolds-averaged numerical simulations (RANS) are performed for the flow and scalar dispersion through a strongly curved open-channel bend. The aim of the study is to investigate the performance of both LES and RANS as reg ...

Influence of pumped storage operation on flow conditions near intake/outlet structures : in situ measurement using ADCP

Anton Schleiss, Giovanni De Cesare, Michael Müller

In the framework of a research project studying the influences of pumping/turbine modes on turbulence, flow fields and suspended sediments in reservoirs, prototype measurements are carried out at the Grimsel II pumped storage plant (Switzerland). In situ r ...

Experimental investigation of unstrained diffusion flames and their instabilities

Etienne Robert

In this thesis, thermal-diffusive instabilities are studied experimentally in diffusion flames. The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional ...

The Local Structure of Atmospheric Turbulence and Its Effect on the Smagorinsky Model for Large Eddy Simulation

Marc Parlange, Charles Vivant Ignacio Meneveau

Phenomena such as large-scale shear, buoyancy, and the proximity to the ground surface significantly affect interactions among scales in atmospheric boundary layer turbulent flows. Hence, these phenomena impact parameters that enter subgrid-scale (SGS) par ...

Coded Modulation Based on Higher Dimensional Chaotic Maps

Thomas Schimming, Slobodan Kozic

In this paper we examine coded modulations based on iterations of higher dimensional piece-wise linear maps(PWLM). Particulary, we study a generalization of the Bernoulli map in higher dimensions and its application to communications. In the proposed schem ...

Numerical simulations of mixing in an SMRX static mixer

Albert Renken, Thierry Meyer

The present work focuses on the flow characteristics and mixing induced by Sulzer SMRX static mixers. It is obsd. both exptl. and numerically that pressure drop increases linearly with velocity for this mixer type and that, as expected, this effect is ampl ...

Numerical experiments on dispersion in heterogeneous porous media

Andrea Rinaldo

The paper discusses numerical simulations of dispersion processes of inert solutes in two-dimensional random log-permeability fields Y(x). A suitable number of realizations is generated preserving a given spatial correlation structure. For each realization ...
