Automatic Block Decomposition of Parametrically Changing Volumes Décomposition automatique par blocs de volumes variables paramétrisés

Oil & Gas Science and Technology, 2006
A method is introduced for the automatic decomposition of time-varying volumes such as those encountered in engine FEA and CFD. Examples of the application of this method to all-hexahedral mesh generation are also presented.

Écoulements au-dessus de macro-rugosités artificielles constituées de plots

Knowledge and Management of Aquatic Ecosystems, 1999
Les écoulements au-dessus de macro-rugosités, dans lesquels les dimensions des éléments rugueux sont du même ordre de grandeur que les profondeurs des écoulements, trouvent de nombreuses applications dans l'hydraulique environnementale, en particulier ...

Quantitative Modelling of Immiscible Displacement in Porous Media. a Network Approach Modèle quantitatif pour l'étude des déplacements non miscibles en milieux poreux. Modèle à reseau maillé

Oil & Gas Science and Technology, 2006
Adequate quantitative models for studying immiscible displacement in porous media are presently not available. This is probably due ta thé extreme complexity of the displacement phenomena, pore structure and lack of understanding of the basic mechanisms.

Cache‐Cache: Dans les souffles du Grand Fleuve…

Anthropology of Consciousness, EarlyView.
ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.

Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I

International Journal of Cosmetic Science, EarlyView.
Repeated exposure to ozonated water caused cumulative oxidative changes in hair, altering structural integrity, thermal behaviour and mechanical properties. The findings reveal a distinct ozone‐induced damage profile that progresses beyond the cuticle, challenging claims of hair‐revitalizing benefits. Abstract Objective Ozone has recently been marketed

Multi‐objective maritime vessel routing with safety considerations

International Transactions in Operational Research, Volume 34, Issue 1, Page 337-371, January 2027.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Impact of Uncertain Parameters on Navier–Stokes Equations With Heat Transfer via Polynomial Chaos Expansion

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.
This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.
