An approximate single fluid 3-dimensional magnetohydrodynamic equilibrium model with toroidal flow

Olivier Sauter, Jonathan Graves, Wilfred Anthony Cooper, Trach-Minh Tran, David Pfefferlé, Jonathan Marc Philippe Faustin, Daniele Brunetti, Madhusudan Raghunathan

An approximate model for a single fluid three-dimensional (3D) magnetohydrodynamic (MHD) equilibrium with pure isothermal toroidal flow with imposed nested magnetic flux surfaces is proposed. It recovers the rigorous toroidal rotation equilibrium descripti ...

Improved Lighthill fish swimming model for bio-inspired robots: Modeling, computational aspects and experimental comparisons

Auke Ijspeert, Mathieu Porez

The best known analytical model of swimming was originally developed by Lighthill and is known as the large amplitude elongated body theory (LAEBT). Recently, this theory has been improved and adapted to robotics through a series of studies ranging from hy ...

Physiological simulation of blood flow in the aorta: comparison of hemodynamic indices as predicted by 3-D FSI, 3-D rigid wall and 1-D models

Alfio Quarteroni, Nikolaos Stergiopoulos, Simone Deparis, Philippe Reymond, Paolo Crosetto

Interest in patient-specific blood-flow circulation modeling has increased substantially in recent years. The availability of clinical data for geometric and elastic properties together with efficient numerical methods has now made model rendering feasible ...

Partial slip at fluid-solid boundaries by multiparticle collision dynamics simulations

Giuseppe Foffi, Maxim Belushkin, Samuel Hanot

The understanding of the exact boundary conditions at the interface between a solid and a fluid is becoming increasingly important, as the limitations of the no-slip boundary condition are becoming apparent, especially in micro- and nanofluidics applicatio ...

Vegetation establishment in convectively accelerated streams

Paolo Perona, Benoît Crouzy, Peter Molnar

We study the conditions for vegetation establishment within river reaches with converging boundaries. Common to many such rivers worldwide is the existence of a limiting front (e.g., Figure 1a) beyond which all the riverbed vegetation is uprooted by floodi ...

Incremental Model Identification of Gas-Liquid Reaction Systems with Unsteady-State Diffusion

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan, Benoit Till Cretegny

Identification of kinetic models and estimation of reaction and mass-transfer parameters can be performed using the extent-based identification method, whereby each chemical/physical process is handled separately [1-3]. This method is used here to analyze ...

On the electrostatic potential in the scrape-off layer of magnetic confinement devices

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

The mechanism regulating the equilibrium electrostatic potential in the scrape-off layer (SOL) of magnetic confinement devices is elucidated. Based on a generalized Ohm's law and the boundary conditions at the magnetic presheath entrance, an analytical exp ...

Effect of available entrainable material on a viscous gravity current including run-out characteristics and internal flow properties.

Christophe Ancey, Belinda Margaret Bates

It has long been accepted that entrainment of loose material by geophysical gravity flows such as dense snow avalanches and debris flows may change their behaviour significantly. Run-out distances and bulk-flow velocities are notable examples of susceptibl ...
