Microcontaminant degradation in municipal wastewater treatment plant secondary effluent by EDDS assisted photo-Fenton at near-neutral pH: An experimental design approach
César Pulgarin, Stefanos Papoutsakis
This work aims to evaluate the applicability of EDDS (ethylenediamine-N,N'-disuccinic acid) as an iron chelating agent for photo-Fenton treatment of municipal wastewater spiked with organic contaminants at near-neutral pH. A series of laboratory scale expe ...
Elsevier2015Flow simulation of a Pelton bucket using finite volume particle method
François Avellan, Ebrahim Jahanbakhsh, Christian Vessaz
The objective of the present paper is to perform an accurate numerical simulation of the high-speed water jet impinging on a Pelton bucket. To reach this goal, the Finite Volume Particle Method (FVPM) is used to discretize the governing equations. FVPM is ...
International Association For Hydraulic Research2014Turing pattern formation driven by cross diffusion for a superdiffusive Lotka-Volterra competitive model
We focus our attention on the effects of introducing the fractional-in-space operator into a Lotka-Volterra competitive model describing population superdiffusion. First, we are interested in how cross superdiffusion influences the formation of spatial pat ...
2014Numerical investigations of the dynamics of the full load vortex rope in a Francis turbine.
François Avellan, Andres Müller, Nicolas Ruchonnet, Olivier Braun, Adrien Taruffi
The draft tube vortex rope occurring in Francis Turbines at full load is a potential cause of severe system instabilities, limiting the operating range of concerned hydro power plants. Studies focusing on physical mechanisms [1], methods for stability asse ...
2013Numerical simulation of orbitally shaken viscous fluids with free surface
Alfio Quarteroni, Florian Maria Wurm, David Hacker, Marco Discacciati, Stéphanie Tissot, Samuel Quinodoz
Orbitally shaken bioreactors are an emerging alternative to stirred-tank bioreactors for large-scale mammalian cell culture, but their fluid dynamics is still not well defined. Among the theoretical and practical issues that remain to be resolved, the char ...
Wiley-Blackwell2013Activation models for the numerical simulation of cardiac electromechanical interactions
Alfio Quarteroni, Ricardo Esteban Ruiz Baier, Simone Rossi
This contribution addresses the mathematical modeling and numerical approximation of the excitation-contraction coupling mechanisms in the heart. The main physiological issues are preliminarily sketched along with an extended overview to the relevant liter ...
Springer2013Numerical Simulation of Sailing Boats: Dynamics, FSI, and Shape Optimization
Alfio Quarteroni, Gianluigi Rozza, Nicola Parolini, Matteo Lombardi
The numerical simulation of free-surface flows around sailing boats is a complex topic that addresses multiple mathematical tasks: the correct study of the flow field around a rigid hull, the numerical simulation of the hull dynamics, the deformation of th ...
Springer2012Numerical simulation of a new sand trap flushing system
Giovanni De Cesare, Milad Daneshvari
Typical sand trap flushing systems, such as Büchi and Dufour, require water volumes up to six times the deposited sediment volume for efficient flushing. Furthermore, complete sediment removal particularly in Dufour sand traps can only be realized with dra ...
2012Hydrodynamics of a Pump-Turbine at Off-Design Operating Conditions: Numerical Simulation
François Avellan, Mohamed Farhat, Vlad Hasmatuchi, Steven Roth, Francisco Botero
Flow numerical simulations in a low specific speed radial pump-turbine scale model are performed to investigate off-design operating conditions in generating mode. The Best Efficiency Point (BEP) and the runaway operating conditions at 10° guide vanes open ...
2011The influence of shear layer thickness on the stability of confined two-dimensional wakes
François Gallaire, Luca Biancofiore
The influence of confinement onto the inviscid and incompressible linear stability of the family of wakes introduced by Monkewitz [Phys. Fluids 31, 999 (1988)] is examined. The nondimensional parameters of the model, the velocity ratio Λ, defined as ratio ...
