Reactive transport, mineral dissolution and precipitation in fractured and porous rock: experiments, models and field observations (session à EGU 2019)

j’aimerais faire la publicité d’une session que je co-organise à la prochaine assemblée de l’EGU à Vienne du 7 au 12 avril prochain:

Reactive transport, mineral dissolution and precipitation in fractured and porous rock: experiments, models and field observations
La date limite pour proposer un abstract est le 10 janvier 2019.

Numero de notre session : HS8.1.7 abstract:
Dissolution, precipitation and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.
With the advent of modern experimental techniques, these processes can now be studied at the microscale, with a direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.
We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).

Rencontres Mécanique-Physique : matériaux actifs (Congrès Français de Mécanique – Brest Août 2019)

le Congrés Français de Mécanique se déroulera du 26 au 30 août 2019 à Brest et comprendra en particulier un Mini-Symposium (M1) – Rencontres Mécanique-Physique : matériaux actifs

DEADLINE pour les soumission : le 15 janvier 2019

M1 – Rencontres Mécanique-Physique : matériaux actifs

Christophe Eloy et Benoît Roman

Une carrosserie dont la forme change sous l’effet de la vitesse, des panneaux solaires qui suivent le soleil à la manière des tournesols… Voici des exemples de matériaux actifs « intelligents » dont la forme est modifiée par la pression, la température, l’humidité, etc. L’objectif de ce mini-symposium est d’avoir un aperçu de la recherche sur ces matériaux actifs, qu’ils soient naturels ou artificiels. Ils posent en effet des questions complexes de mécanique et de physique (grandes déformations, non-linéarités, couplages multi-physiques, instabilités).

Ce mini-symposium, à l’interface entre la science des matériaux, la mécanique des solides, les interactions fluide-structure et la biologie, abordera les thèmes suivants (liste non limitative) : la robotique souple, les matériaux programmables, l’extraction d’énergie de l’environnement, différents types d’actuation, la modélisation de la croissance et de la morphogenèse, etc.

Ce mini-symposium se place sous le double label de l’Association Française de Mécanique (AFM) et de la Société Française de Physique (SFP).

Journées de physique statistique (31 jan / 1er Fev 2019 – Paris)

For the 39th time, the « Journées de Physique Statistique » will be organised soon (Thursday Jan 31-Friday Feb 1 2019 at Ens Paris). They will consist of 12 long presentations, the rest of the time being devoted to flash talks as in previous editions.

Essential informations:

1. The meeting is informal, and no financial support will be available.

2. Given the brevity of the flash talks (4 minutes), the essence of the problem and main results only can be presented, without entering into the details.

3. Participation is free. Only those intending to present a flask talk should register.

4. Deadline for registration (http://jstat.phys.ens.fr/) is on ** Dec 20 2018 **

5. Participants who subscribe for flash talks will be recontacted to upload their slides. The corresponding file will be sent in pdf format before Jan 14 2019

6. The programme will be available on Jan 17

More details are available on http://jstat.phys.ens.fr/

Avalanche Dynamics and Precursors of Catastrophic Event (Les Houches, Feb. 2019)

Workshop Announcement: Avalanche Dynamics and Precursors of Catastrophic Event (Les Houches, Feb. 2019)

________________________
Dear colleagues

we are writing you to announce the workshop

Avalanche Dynamics and Precursors of Catastrophic Events

Les Houches (France), 4-8 February 2019

The workshop aims at gathering scientists working in varied research topics
involving intermittent behaviours associated to strongly correlated dynamics.

Examples range from the atomic to the tectonic scale, including avalanches in
magnetic materials, superconductors, deformation of glasses, cascades of
rearrangements in soft matter systems, critical dynamics of imbibition fronts
and crack growth; mechanical response of granular and porous media, wood,
and geological flows, such as snow avalanches and earthquakes.

Understanding the complex, nonlinear spatio-temporal response of these systems,
is crucial for physical predictions and for the development of reliable models. Recent
theoretical and experimental progress makes this a timely forum for an interdisciplinary
effort to advance this important emerging research area.

Topics of the workshop include:
Conditions for universality (and non-universal features) in avalanche dynamics
Precursors of catastrophic events
Avalanches in transient dynamics
Depinning and yielding transitions
Instability in solid earth systems
Coarse grained models for avalanche dynamics

Detailed information for participating and submitting an abstract can be found
on the workshop’s website
https://avalanche2019.sciencesconf.org/
together with the list of invited speakers.

Inscriptions to the worshop are welcome, those with abstract being favoured.
The deadline for abstract submission is: November 1, 2018
