Kinematic dynamos in triaxial ellipsoids
Jérémie Vidal, David Cébron
Planetary magnetic fields are generated by motions of electrically conducting fluids in their interiors. The dynamo problem has thus received much attention in spherical geometries…
Acoustic and inertial modes in planetary-like rotating ellipsoids
Jérémie Vidal, David Cébron
The bounded oscillations of rotating fluid-filled ellipsoids can provide physical insight into the flow dynamics of deformed planetary interiors. The inertial modes, sustained by t…
Acoustic modes of rapidly rotating ellipsoids subject to centrifugal gravity
Jérémie Vidal, David Cébron
The acoustic modes of a rotating fluid-filled cavity can be used to determine the effective rotation rate of a fluid (since the resonant frequencies are modified by the flows). To…
Portlandite solubility and Ca2+ activity in presence of gluconate and hexitols
Lina Bouzouaid, Barbara Lothenbach, Alejandro Fernandez-Martinez +1
The current paper investigates the impact of gluconate, D-sorbitol, D-mannitol and D-galactitol on calcium speciation at high pH values by i) solubility measurements of portlandite…
A controllability method for Maxwell's equations
T. Chaumont-Frelet, M. J. Grote, S. Lanteri +1
We propose a controllability method for the numerical solution of time-harmonic Maxwell's equations in their first-order formulation. By minimizing a quadratic cost functional, whi…
Ultrasonic monitoring of stress and cracks of the 1/3 scale mock-up of nuclear reactor concrete containment structure
Qi Xue, Eric Larose, Ludovic Moreau +3
To evaluate the stress level and damage of a reinforced concrete containment wall and its reaction to pressure variations, we implemented successive ultrasonic experiments on the e…
